(cherry picked from commit f5f0b5e76c2fd405c8cc895dde653c5ed2652622)
* S_Init -> S_InitSfxChannels because it did mostly SFX anyway
* S_MusicPlaying, S_MusicPaused, S_MusicName, S_MusicExists new status methods
* I_MusicPlaying, I_MusicPaused
* Re-purpose I_LoadSong for digital music loading
* I_StartDigSong logic split between I_LoadSong and I_PlaySong
* Pause, Stop, and Unload routines are combined from Digi and MIDI
* music_lumpnum, music_data, music_handle from s_sound.c are gone
* Kill addonsresponselimit, which was a hacky solution to a stupid problem. Instead...
* Allocate and consistently handle memory to store the name of an added file so we can reference it directly.
* Replace the choice between ./ and a custom folder with the full, standard assortment of Default (usehome ? SRB2HOME : SRB2PATH), HOME (SRB2HOME), SRB2 (SRB2PATH) or Custom (cv_addons_folder.string).
* Make these render as the name plus folder, since you can't go UP... from the top level.
* Make the path seperators consistently system-based re PATHSEP. (Quite frankly, I'm surprised it even worked in the first place...)
* Instead of iterating through the folder every time you change the search query by one letter, iterate through the "coredirmenu" (the game's interpretation of the folder) instead. MUCH, much less likely to lag to fuck and back.
* Hide a bit of complexity in filesrch.c instead of having the entire thing exposed to mess with. For example, closefilemenu() instead of manually freeing the struct each time.
* Refactor some stuff.
* Actual indication of modified game status on the addons menu.
* Yes, I know this has nothing to do with the branch, I'm just doing little things I found useful.
* Enable SECTORSPECIALAFTERTHINK since we probably really want to use that sloped lava wave in RVZ.
* Allow for infinite lives to be set via the setlives command/Pandora's Box.
* Refactor P_DoFiring(), with guidance from Sal.
* Correct the CRAWLA HONCHO\nCAN NOW BECOME\nSUPER CRAWLA HONCHO sliding movement in non-green resolutions.
* Bomb sphere! Paraloopable hazard. Replaces MT_SPECIALSPIKEBALL.
* Blueberry bushes, both normal and Xmas, from patch.dta.
* BSZ tulips, also from patch.dta!
* Frozen Hillside badniks - Penguinator and Pophat.
* Frozen Hillside ice decoration!
* Fixed some big bugs with the DSZ light beams.
* Made multi-mare special stages work, in a troll way - the Chaos Emerald disappears in a puff of smoke, and the Spinbobert laughter sound plays... >:3c
* Reverted the mobjtype number changes from the source SOC/Lua, which we can do later when doing a final pass of the levels.
* State optimisation.
* Serious cruft-removal of the NiGHTS drone thinker.
* Fix the issues where the player wouldn't curl into jump in waterslides or dropping off rope-hangs.
* Tweak NiGHTS player flashing.
* Add text colour support to the titlecard font.
* Use that to make the PRESS SPIN\nMID-JUMP thing when you get all Chaos Emeralds use the titlecard font for readability.
* Fix the GOT ALL EMERALDS page not lasting the correct, extended amount of time.
* Fix that thing where flying mid-spin didn't enact autobrake.
* Modify graymap a little on Sryder's suggestion.
* [COMPLETELY UNRELATED] fix that thing where the addons menu will fail on files/paths with spaces in [/COMPLETELY UNRELATED]
* cv_powerupdisplay. Never, First-person only (default), Always.
* New monitor stuff.
* Fixed hitmessages.
* Some CTF stuff.
* Aaaaugh it's a lot I hate myself I need to work on my coursework.
* I'll figure out what I did here in the merge request when that's done.
* Make TIME part of HUD count down in a bunch of circumstances where it was otherwise some other seperate thing.
* Make race countdown happen in a bunch of appropriate circumstances.
* Refactor race countdown.
* Remove a lot of useless stuff from H&S/Tag UI.
* Make co-op/competition/race end-of-act countdown use the race countdown and bigger HUD font.
* Remove useless PLAYING/SPECTATE text from lives element.
* Merge lap counter into lives element.
* Move some other text around.
