* Stop orphaning their memory. They ARE PU_LEVEL, so they'll disappear eventually, but, like... it's not good memory management practice to just *orphan* them when you're literally never going to do anything with them ever again. Y'know?
* Make ghosts spawn properly on slopes.
* Turn off mlook and mousemove by default, as requested by Prime/Mystic.
* Change all the analog cvar names (and hide them from the help function so they aren't so easily rediscovered) to invalidate 2.1-era copies of config.cfg, given I've seen a common sentiment is that they won't try the new controls at all and will just copy their old ones across, and I'd like to sabotage the deprecated feature.
OLD SPECIAL STAGES:
* Spheres in old special stages instead of rings!
* Individual timers in old special stages instead of a global one!
* Old special stages use a variant of the NiGHTS HUD now!
* Special stage damage in old special stages loses 5 seconds of time instead of 10 rings/spheres!
* All damage gained through old special stages is converted to special stage damage! As a consequence, the special spikeball has no need to be special anymore.
* Made emerald gaining function be based on special stage number rather than gained emeralds!
* Consistency with...
NiGHTS SPECIAL STAGES:
* Spheres now flash in bonus time. https://cdn.discordapp.com/attachments/400761370800422922/452590553100713984/srb20032.gif
* Sphere and ring mapthingnums are now less fucked up in 'em. (Rings are 300, same as usual, while Spheres are now 1706 replacing NiGHTS Wings.)
SPECIAL STAGES IN GENERAL:
* useNightsSS is now dead. Each individual special stage is now assessed for NiGHTS-mode behaviour based on maptol & TOL_NIGHTS.
* CRAWLA HONCHO\n CAN NOW BE\n SUPER CRAWLA HONCHO end tally modification now also includes a mini-tutorial on turning super. https://cdn.discordapp.com/attachments/400761370800422922/452844894113759233/srb20036.gif
* SONIC GOT A CHAOS EMERALD? https://cdn.discordapp.com/attachments/400761370800422922/452623869497573386/srb20034.gif
NiGHTS NON-SPECIAL STAGES:
* Colour Chips and Star Chips! Replaces Spheres and Rings of NiGHTS Special Stages.
* Colour Chips turn yellow in bonus time.
* Ideya!
* Its own "drowning" music!
* All of the object types for Dream Hill.
* GIF: https://cdn.discordapp.com/attachments/400761370800422922/452844894113759233/srb20036.gif
RANDOM BS:
* Turn super with the spin button instead of the jump button!
* Followmobj now correctly set with P_SetTarget instead of pointer assignment.
* Emerald hunt uses new sprites!
* Made unlock noise different from emblem gain noise! (It's the CRAWLA HONCHO CAN NOW TURN yadda yadda sound from S3K now.)
* Prevent ANY input when blindfolded.
* Make CECHOs always perplayer'd. (A little hacky; quads will need work here.)
* Make NiGHTS link timer bounces not a mess, and only when the colour changes.
* Rename GZT_SPRITE to GZT_FRAME, since otherwise it's easy to confuse with EZT_SPRITE (which does something completely different).
* Fix issue where ghosts were facing wrong direction on spawn.
* Other minor refactorings.
* ...also, made smiles' tails pop up instead of down when skidding
