Web stuff for Ludum Dare 47

This time our team decided to write our game for the browser, so that it would be easier for people to play. I didn't really like any of the engines I saw out there, and doing things from scratch is more fun, so here is some code that might prove useful to our fellow jammers. Presently, this repo has:

• math32.js : A medium-performance linear algebra library designed for handling the f32 values that WebGL takes in for uniforms. It can be used in both zero-allocation and maximum-convenience modes depending on whether you call the functions with names like addeq or the ones like add (which allocate). See all those places I used Math.fround? Apparently that tells the JIT that it can use f32 operations. I checked with profiling and it's actually about 10-20% faster! You can read about it (here)[https://blog.mozilla.org/javascript/2013/11/07/efficient-float32-arithmetic-in-javascript/]. Benjamin Bouvier put the optimization in Firefox. Hopefully that new JIT that they're about to release still has it! (I heard they were tracking less type information...)

Other stuff

You can see a log of all my bad ideas in notes. Also there's the start of something about webGL audio in audiodemo.html. The Negentropy mp3 which I'm using as a test file was written by the very cool Chad Crouch.
