* 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.

* 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.

* 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.
