* Update the function signature of P_MixUp to accomodate both it and drawangle instead of doing it outside of the function.
* If the player is spawning from the start of the stage and it's from the ceiling, be in fall frames as requested (resolves#191).
* PF_NIGHTSMODE is now CR_NIGHTSMODE as part of player->powers[pw_carry]. This is because it's mutually exclusive to every other "carry" type.
* PF_SUPERREADY is dead because it literally just checked for all 7 emeralds and 50 rings. That's it. You couldn't even appreciably alter its presence with Lua. That logic has been placed back in P_SuperReady.
