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.)
