Many new move animations

Added new animations for Precipice Blades, Origin Pulse, Dragon Ascent,
Diamond Storm, Tri Attack, Signal Beam, and Moonblast.

Also based a lot of moves off other animations so they don't use default.

Changed Sky Drop's animation because people were saying the current 
animation was weird during the first turn.

This isn't actually done yet; I just want everyone's feedback. I'm still trying 
to figure out what the best animation for Thousand Arrows is, for starters.
