Pulsar Starlight Audio Visualizer

It's not really a question of what I did do? It's more like what didn't
I do? The audio engine now splits audio into separate left & right
channels, visualizes them separately then rejoins them for final output.
It has a master gain and dynamics compressor to finally tame the web's
volume knob. And, Pulsar's SoundCloud player has incredible visuals.

It's a big changelist.
