Ace Mechanics

- Fixed Ace's animation so it wouldn't continue to play the animation
from where it left off
- Added so when ace is slicing he can't switch directions; he can't jump
or move if he's slicing on the ground
- Ace will stop his jump slice if he hits the ground
- Ace won't spam jump or slice if the user holds the jump/slice key down
now
- When ace finishes his jump slice, his animation changes to jumping. If
ace finishes his ground slice, his animation changes to standing.
