Sink shield that makes it double-press to use, gives the trailing item slowdown, and shows other people that you have it, but doesn't have any collision
* Make MT_GHOST's encoremapping depend on whether the source was encoremapped.
* Revamp how sector typegroup 2, type 15 inverts the encoremapping (so planes don't get awkwardly desynchronised).
* Flashing Eggman-hit players.
* Fix typo with Rocket Shoe item bar, and make it extensible for potential future purposes since I was fiddling with it anyways.
* More complete playerarrow visuals for various items.
* Eggman fake (and debug) item get sounds.
* Default hitbox height is 80
* Drone Thing parameter sets height to multiples of 32
* Player aligns by default to bottom+24 of hitbox (offsetted)
* `MTF_OBJECTSPECIAL` aligns player to hitbox top
* `MTF_EXTRA` aligns to hitbox center
* `MTF_OBJECTSPECIAL|MTF_EXTRA` aligns to real bottom of hitbox
* Goalpost and sparkle Z alignment is changed to reflect configurableness
* New entries: NIGHTSDRONE_MAN, NIGHTSDRONE_SPARKLING
* NIGHTSGOAL renamed to NIGHTSDRONE_GOAL
* MT_NIGHTSDRONE repurposed as an invisble, no-gravity hitbox
* HOWEVER, we should seriously address this again later, because the antialiasing DOES result in some unfortunate bullshit...
* Encoremap maces per Oni's request and Sal's suggestion
* Objects!
* Gone is the arcane, difficult-to-remember list of random flags. Say hello to MF_DONTENCOREMAP!
* Alternatively, if the object has a skincolour applied to it, it isn't encoremapped either. (Useful for ghosts, for example.)
* Sectors!
* The autodetecting of sneaker and spring panels is now much more intelligent, and only avoids remapping the plane(s) the effect is availible upon.
* Sector special group 2 no. 15 is now "Invert Encore Remap". It inverts the above detection.
* Linedefs!
* The "Transfer Line" linedef flag can now also be used to deny Encore remappings on linedef textures.
* Right now it applies to every pixel drawn specifically belonging to that linedef, but if people decide it needs changing, we CAN make it apply to midtextures only (like linedef types 900-910).
* Make Orbinaut Shields animate at 3 tics per frame, not 1.
* Make dead items flash in and out of visibility.
* Related to above, fix a few circumstances where returning was not properly handled after removing a mobj in mobjthinker.
- Ballhog has explosion + sound on death
- Ballhog shrinks to nothing if it didn't hit anything
- Replaced a Mario sound on Orbinaut
- Fixed Jawz's sound effect
- Fixed Mines not being removed on death pits
* Palette remaps.
* Branding.
TODO:
* Doesn't work in GL. (Mostly.) I have SOME ideas on how to tackle this, but...
* Transmaps are broken in Encore for some reason.
* I tried to make in-level colormaps shimmy over, but it didn't quite work, so I commented it out and only semi-fixed it.
- You can bump other people during spinout.
- Bumping during spinout activates a "slow down" timer, which increases your friction after a few tics.
- You have a Smash-style dust effect after a spinout bump, indicating clearly if you'll slow down or not.
- Spring panels have a higher minimum forward speed, and you can no longer drop below that speed.
- New, separate type of spring panel that has a maximum speed cap, for small jumps.
- Unrelated: The SMK Donut Plains bushes now have much less thinker overhead.
- Unrelated: Fixed my earlier attempt at getting momentum redirect to work when you just hit the ground.
* Make MT_GHOST's dispoffset -1, so that at the starting line in record attack your player is always visible even when you have multiple ghosts in play.
