Update README.md
Updated UI

Updated the UI to look better, all buttons work the same, no ID's have
changed (except loadingDialog changed to loadingIcon). Added functions:
showQueue and hideQueue which causes the panel on the left to open to
show the songQueue. Also added the function appendSong which will add a
song to the queue visually
Created a shader for our frequency visualizer

The js\shaders director will be where we store shaders, please use the
naming convention of "shader-name-fragment" or "shader-name-vertex" for
vertex vs fragment shaders.

We can load the shaders using the new function: loadShader(filepath).
This is simply an ajax request to load a file as text, which is what a
shader takes as input.
color-height shader no longer mirrors

Just a small change to how the shader does vertical coloring.
Cleaning up the code, removing orphans
