* Prevent an infinite quantity of Emeralds being spawned when P_GiveEmerald is called while a MP Special Stage is in session (resolves#347).
* Fix FuriousFox's ridiculous timer on special stage spawn (mentioned in the comments of the previous issue) by correctly marking spectator players in special stages as finished, and preventing the underflow.

It turns out that in Sonic 3 & Knuckles, the threshold for crossing into the super animation is increased compared to normal gameplay. This makes a lot of sense - however, both Sonic Mania and the Taxman/Stealth mobile remakes missed this. I quickly tested and confirmed that SRB2 had the same issue, so here's the fix.
* Expose this via additional upper-16-bits flags of A_FlickySpawn.
* Use this to make Snailers not spawn their flicky inside the wall they're attached to.
* Make the behaviour of Egg Capsules more consistent mechanically regarding the flicky spawning, using the above as one relevant element.
Make the wall transfer while spinning PF_SPINNING|PF_THOKKED. This:
* Prevents PF_MULTIABILITY players from using their ability after a wall transfer.
* Has a more specialised case which allows players to roll after having wall-transferred while spinning.
* (side effect) allows modders to apply PF_THOKKED any time for more controllable spinning.
* When activated, stops the timer in SP/MP.
* Applies to the mapheader countdowntimer as well.
* If you're playing Record Attack, also exits the level immediately.
* It has no special modes, no linedef flags, no parameters, nothing.
* Only not an innate property of A_BossDeath because people may want it to NOT happen sometimes, or make it happen with non-boss events too.
Also, skip over calling P_DoPlayerExit if the player isn't in game.
* Disable lives when Metal recording (and have a big flashing REC instead, because I'm a riot).
* Correct some minor directionchar issues (some introduced in this branch, some not).
* Add height changes to demos and Metal playback (to properly place thok aura relative to object).
* Fix followmobj recordings in reverse gravity (done via more strenuous flag setting + info height serialisation).
* Make RA ghosts fade in from start tic, and go colorized on their final one.
* Fix thok auras potentially doing bad things if they're set to MT_NULL.
* Add sprite change support to Metal playback.
* Re-enable some stuff I previously disabled for Metal recording/playback.
* Make ALL objects spawned with skins properly acknowledge that their spawnstate's frame is a sprite2, rather than just specific objects.
* Fix placement of Metal Sonic fume in reverse gravity.
* Since not backwards compatible with the previous test build, increment DEMOVERSION again. (Don't worry, we've got like 65524 more versions allowed before we run out of possible DEMOVERSIONs...)
* Make the skin to record with Metal rather than Flesh Sonic. (Allowed even if not unlocked!)
* Make the object that plays back the recording actually use the Metal skin, rather than just a seperate spriteset. (The boss will still need the spriteset, though.)
* Actively record the player's sprite2, frame, and followmobj, just like regular ghosts do.
* Disable dashmode while recording, for a fairer race.
* Fix a probably long-standing bug where, while recording, being "hurt" would get Metal stuck in pain frames until they physically left the area of hurt.
* Always start Metal recording in wait frames for bonus taunting.
Other relevant changes:
* Increment DEMOVERSION *again*.
* Improve the Record Attack ghost followmobj recording to accomodate Metal's jet.
* Increase the datatype width of spritenum_t read/write for Record Attack ghosts because SUGOI 4: Back With A Revengance will probably also use more than 255 sprites alone.
* Return to standing frames (or prolong them if you're in them, rather than going to wait frames) if the player rotates on the spot with enough force.
* This was specifically done *for* Metal recording, but I decided it looked good enough to enable all the time.
* Fix music stack corruption in multiplayer where a super player dies and it's not you.
* Fix players in minecarts having their state eternally set to S_PLAY_STND (bug discovered/evident while super, so goes in this branch).
Resolves#259.
Music pausing is now optional.
Sounds may be paused--on by default.
The game itself being paused in off-line mode is now optional.
(showfocuslost now loads from config.)
* Red and yellow Boost panels!
* Added because SUBARASHII and KIMOKAWAIII had several levels using them, and I wanted to make them look better.
* https://cdn.discordapp.com/attachments/359091121789468672/634486669202161674/srb20015.gif
* Uses the mapthingnums of Glaber's SOC resource boosters, but absolutely nothing else - not even the magnitudes.
* Apply MF_AMBUSH to force the player into a spin - even if they don't have a spin ability!
* Banpyura!
* A Crushstacean with a spring instead of a crushclaw.
* https://cdn.discordapp.com/attachments/428262628893261828/634432099306176512/srb20019.gif
* Wanted this for a while, finally added it.
* Improved springs.
* Add pw_noautobrake to disable autobrake for half a second when touching yellow horizontal springs, and a second when touching red ones, even on the ground.
* Add pw_justsprung to disable directionchar for a few tics while touching any springs with a horizontal component to their velocity.
* Add the diagonal spring flag options Red and Yellow Diagonal Springs have to the Blue Diagonal Spring as well.
* Started but decided against a tip of the hat to the CD spring spin, hidden behind #define SPRINGSPIN.
* Make directionchar "lag behind" a little bit in waterslides.
* Improved flame jets.
* They now use new sprites for having their flames move upwards and sideways, instead of having them always face downwards like in 2.1!
* Fixed a mixed declaration and code error in A_RolloutRock. (Sorry Lach!)
* Make the Amy Cameo only spawn in SP, Record Attack, or Co-op unless it's the Clone Mode.
* Improved ZB config.
* Add above new types.
* Add Blue Diagonal Spring, which existed in the source but not the config.
* Re-order enemies in ZB config by zone (but keep them in the Enemies section only).
* If using twinspin and have melee ability too, go into melee landing when hitting the ground.
* Only have melee go directly forward if standing/idle, otherwise use drawangle.
Glide speed now starts at whatever speed you were traveling at prior.
If glide speed is below actionspd, the glide accelerates towards it.
When landing from a glide, player now enters a landing animation (SPR2_LAND); they cannot move in this state, but they can jump or start a spindash.
Ground-sliding after a glide can now be cancelled into the landing animation by releasing jump, where the same rules apply.
Climb speed increased x1.33.
* Prevent being able to damage enemies from below while swimming.
* Make the swim-specific bubbles happen at the hands instead of where the propeller would be.
* Improve placement/angle of swimming tails overlay.
* Immediately set flight time to 0 if a player is being carried underwater.
* Fix S_PLAY_FLY_TIRED animation being fast.
* Add moving tails to S_PLAY_SWIM animation!
* Fix autobrake happening when your controls are locked by pw_nocontrol/PF_STASIS. (Resolves#219, hopefully..?)
* Put everything in P_DoJumpStuff, instead of half in that function and half spread across the player thinker.
* Have a proper if else cascade that first tries shield abilities, then super transformation, then random abilities like CA_TELEKINESIS.
* Use this new arrangement to allow CA_TWINSPIN users to use their ability on spin if their secondary ability is CA2_MELEE (resolves#195).
* Random bugfixing. Didn't keep track of what I'd caused while working on this and what was already there, but there was a lot of it.
The only two abilities which have spin-button properties outside of the else block is CA_AIRDRILL and CA_FLY/CA_SWIM (which now also prevents you from swimming down in goowater).
* Don't allow the stage to be reloaded in G_DoReborn.
* If you do ANY spawn after the very beginning moment, you're forced to be a spectator.
* Have the "%d player%s remaining" Co-op exiting count visible at the same time as spectator controls.
* Genesis-style love and attention to the death event.
* Only visibly decrement lives/rings when you're respawning (or game over, see below).
* Faster no-button-press respawn.
* Game Over specific love.
* Animation of Level Title font coming in from the sides.
* https://cdn.discordapp.com/attachments/428262628893261828/617692325438554132/srb20067.gif
* Change gameovertics to 10 seconds instead of 15.
* Make the minimum time before you can force going to the Continue screen longer.
* Accomodate death in MP special stages as a form of exit.
* Don't have your rings or spheres reset when you die in a special stage, so that the stage isn't softlocked with the new harder limits.
* Fix a bug with CoopLives_OnChange where changing to infinite lives didn't force a game-overed player to respawn.
Also, two not-quite death things which nonetheless were relevant to change:
* Fix quitting a special stage having some of the shared spheres/rings disappear into the aether.
* Fix a warning during compilation for the Ring Penalty print.
* Make it actually look like a brake, so people can tell it's on instead of just having high friction.
* Fix it fucking with spring chains (caused by being unwittingly active for the first tic of spring collision).
