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.)

Disable menu input on the title screen for the first second (ie, before the flash), to guarantee people won't start the menu the very first tic after the fade and ruin the animation. (Console and gif/screenshot recording still works, for the impatient.)
