Item roulette fun-times

- Colorize items, Combi-Catcher style, while the roulette is still going. Nice Chaotix reference, and tells you when the game's just lagged.
- Items blink when you first get them! They blink white when you wait out the whole roulette, red when you mash, or rainbow for enhanced items! Blinking prevents items from being stolen too, so items can't be literally stolen before you even have a chance to see what it was.
- New item roulette sound for mashing
- Fix TC_ limits in Lua
