Re-add/fix broken platform momz mobj code.
The changes in this branch re-add the platform's momentum to players and mobjs which leave the platform (eg. by jumping) so that they move with relative velocity as expected. This behavior was unintentionally broken in SRB2 2.0, which adds a lot of artificial difficulty to certain segments of the levels, where you have to jump between high velocity moving platforms which seemingly cut your jump height to nothing.
Not only has the behavior been fixed, but it has now been enhanced to move the camera while free-falling between platforms as well, completing the illusion of full relative velocity with minimal hiccups. [Observe.](http://i.imgur.com/zmSfUyp.gifv)

Miscellanous fixes to merge
These are the commits from the "miscellanous-fixes" branch that are okay to merge in.
Bugs fixed include the following:
* CTF flags respawning incorrectly: they cannot z position themselves correctly, and they cannot flip themselves.
* The weird "jumping" spring/monitor effect: this is the result of an internal mobj_t pointer (tmfloorthing, specifically) not resetting itself to NULL for the next object's thinker, resulting in Z movement code thrusting the object vertically at tmfloorthing->momz.

... because some things (Lua. custom header entries) move it.

(Technically breaks netgame compatibility for Lua-heavy mods, so in next.)
Assume that every frame the player is on the ground, their pmomz will
be re-set properly if the floor is moving, therefore if the platform
STOPS, we need this to set it to 0.
This fixes the issue with upside-down springs shooting downwards if you touch another of its kind. Also fixes one of the issues with monitors in Icicle Falls (after you phase inside the East-most float-bob FOF's monitor via the other bug and jump up to break it while there, the NEXT monitor moves upwards too)
Here's how it works: When a player walks off the
moving platform, it applies their pmomz once, and
then _keeps pmomz set_ so that the camera still
adds pmomz to its movements until they hit another
floor. This way, the camera doesn't jerk around.
Also gain velocity from walking off an "up" elevator normally?
This _looks_ incorrect because the camera stops matching
the platform movement the moment you step off, but I
assure you it is a correct and accurate movement.
(Try it with chasecam off.)
Now players will apply platform movement when jumping,
but only if the platform is moving the same direction
as their jump is, and all other objects will have an
appropriate pmomz in reverse gravity FOF situations.
Actual blockmap fix
MI's "fix" was a reversion of something that allowed 2.0 maps to use the entire blockmap. This MR reverts that fix and adds a proper fix to the issue of west/south edges of the blockmap not working as they should. Tested with a thokbarrier-less square map (all sides were solid) and with AGZ (objects are tangible all around the map, like they are in 2.1.14).

Re-fix the server global variable in Lua
I screwed up the conditions on my first attempt to fix this, since I only tested one scenario. Tested this in SP, at the main menu, and both clientside and (dedicated)serverside in MP. Everything works as intended.

Polyobject more fixes
Extra fixes related to polyobjects; actually properly putting their flats alongside them in the draw list, and making them able to use single-waypoint zoom tube sequences. Also threw in a smoothness fix for swinging chains while I was there.
See merge request !8
Polyobject scroll hotfix
Things fixed:
* Polyobjects should now carry the same thing types as conveyors (notable example; they'll now carry Crawlas when they wouldn't before)
* The drifting issue with players on spinning polyobjects should be fixed. (I swapped in the old bad hack for a new hack that should work like it's supposed to)

...
(It's that infamous intangible West/South linedefs bug, which was really a blockmap-related bug all along. AND IT WAS SO SIMPLE TO FIX!)
