Specfically, this fixes the case where Sonic runs into something hazardous and spills his rings, but Tailsbot is immediately behind and ends up picking them all up the tic before they also get hurt.
* Make it possible to break them in reverse gravity (resolves#348) by making the spikes break in a circle around the spike touched, rather than in a circle around the player.
* Fix the spike chunks spawned not being flipped in reverse gravity by using P_SpawnMobjFromMobj.
* Make their breaking sound singular (prevents eardrum destruction).
* Add an alternate DEMOMARKER for ending the Metal Recording on death, which kills the Metal object as well.
* Add some more relevant exceptions to the "most objects are removed when touching a deathpit" thing, primarily for the sake of ghosts and Metal playback.
* 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.
* 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).
* Tailsbots can't get into Minecarts.
* Tailsbots will stop trying to move around when the player gets pw_carry, which usually means some sort of big gimmick is happening and trying to move along with it would make the tailsbot look stupid.
