* Super sprites are now deliniated via an additional S_SUPER lump between S_START and S_END. Above are normal sprites, below are super sprites. Handled internally via FF_SPR2SUPER.
* Sprite2 numbers are now appropriately limited for the data type that stores them.
* SPR2_SPIN is now SPR2_ROLL, SPR2_DASH is now SPR2_SPIN and SPR2_PEEL is now SPR2_DASH. Makes more sense, right?
* flips the sprite ala MFE_VERTICALFLIP except you don't need to flip the direction of gravity for the object just to draw upside down
* stacks properly with reverse gravity
* FF_MIDDLESTARTCHANCE - has a 50% chance of starting the spr2 or FF_ANIMATE animation halfway in
* FF_SPR2ENDSTATE - if var1 == S_NULL, don't loop, just stop incrementing the frames. Otherwise, go to the state represented by var1.
The former is just something I did for fun, the latter is something that'll come in handy when porting in new-character-moves.
