Patch Notes R3

Not mentioned previously but we put out R2 right after release and accidentally broke the audio, oops!

R2:

• Fixed various WebGL issues in Firefox which prevented anything from being rendered.
• Added deprecated Web Audio API calls for Firefox.

R3:

• Majorly improves robustness of collision and raycasting. Shooting is properly reliable now.
• Fixes an issue where Web Audio was partially broken for Chrome.
• Adds minor geometry changes to map.
