* Make R_SetPlayerSkin check for usability of skin before setting, and error otherwise.

* Also grey out colour if team gametype.

Lach wanted to do this, but we might have a release candidate before he gets back, so did it myself.

Make the wall transfer while spinning PF_SPINNING|PF_THOKKED. This:
* Prevents PF_MULTIABILITY players from using their ability after a wall transfer.
* Has a more specialised case which allows players to roll after having wall-transferred while spinning.
* (side effect) allows modders to apply PF_THOKKED any time for more controllable spinning.
