Complete overhaul of js and file handling.  Adds ability to stream file chunks while recording. See notes.

Adds video/audio stream recording for firefox (video only works in firefox nightly). This will cut down considerable on upload times.
Media recorder only asks for mic permission on record (https://drupal.org/node/2232601).
Better UI with help messages.
Better error handling on both server and client sides.
Added theme template for more customizability.
Added better audio visualization and mic meter.
