Fixed Animations and WebGL Pecularities

We finally got around to fixing the lag in player animations by re-doing the animation state machine from scratch. We based our new state machine on a talk from William Armstrong at Unite 2016.

Our programmer also set up a new environment for rapidly iterating in WebGL using a local web server rather than relying on itch.io's renderer. By using some debugging features, the programmer was able to identify some quirks of the Unity WebGL implementation which were causing bugs with our audio. Some preprocessor directives were introduced to handle WebGL differently from other platforms.
