Polish the code and the UI.

Clean your node_modules and redo npm install.

Core:
+ general performance
+ Not using glslify anymore to keep the comments
+ make the app not crash if examples are not compiling
+ destroy the old buffers and remove from the audio api to avoid leaks
+ split the render / update loop
UI:
+ general UI improvment + move to dark theme
+ Rework of the SoundViz with seamless BufferViz + Animation :-)
+ Only scale in CSS the canvases for better performances
Examples:
+ add bassrythm.glsl and stereo.glsl examples
+ polish sweet_dream.glsl
