Some fixes

- Use SKINCOLOR_PURPLE instead of SKINCOLOR_THISTLE for the drift boost explosion.
- Use steering instead of cmd.turning in a few places. I dunno if I forgot to change these, or if it was accidentally reverted, or what. (Anything with a specific reason to use cmd.turning over steering will have a comment near it saying why.)
