[Vorbis] Vorbis encoding using JavaScript

[Mateusz Wielgos]

Hello,

First of all, I am a complete newblet to anything dealing with audio (a lot
of the vocabulary is still rather mysterious to me). I also don't often
program in C so please don't throw too many stones if my workflow is less
than ideal. :)

I would like to port the vorbis encoder to JavaScript. Instead of porting
everything by hand from ground up, which would take who-knows-how-long, I
am using a tool called emscripten (https://github.com/kripken/emscripten).
