Jailbroken iOS Support

Hi, I'm the developer of Procyon for jailbroken iPhones. iOS 4.2 and higher do support WebGL, but Apple turned it off. In my browser for jailbroken iPhones, I have enabled WebGL and tested out your game as an example that WebGL works. With just a few modifications of the Firefox OS branch, I was able to get gameplay working perfectly on my iPod touch 5.

I've created a separate branch so you can merge it in however you choose :)

Here's a screenshot of me playing with the motion controls (touch controls also work fine too):
