Braedon fa519d25d7 A lot of stuff (Read desc)
Beat action is now used to define one-off objects that is used by the beat but I don't wanna bother making a different script for. Example case: the "hit 3" sprite in Karate Man.

Animation helpers for functions I don't wanna rewrite 100,000 times.

General improvements for Karate Man, like prepare animation and some updates to game events.
