Merge branch 'rotsprite_i' of https://git.magicalgirl.moe/STJr/SRB2Internal.git into rotsprite_toast

* Remove the 22(!!) NiGHTS sprite2s that no longer get used in ROTSPRITE builds (which should be our main builds going forward).
* Rename `SPR2_NGT0` to `SPR2_NFLY`, and `SPR2_DRL0` to `SPR2_NDRL` to account for this. (requires modifying player.dta)

Why was it even disabled anyway.

Other things I missed. Also added SF_NONIGHTSROTATION. Do I even have to keep the old behaviour? I have no idea.

Resolve #281. (Might have problems with non-SDL interfaces, but definitely good for what we're shipping with.)
