This does not change any vanilla behavior, as scoreadd is reset constantly on the ground anyway -- this simply makes the behavior modifiable for Lua scripts.
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.
