Cleaning up repo by moving assets to where they will be once we generate...

... styleguides

Removed all unused files since they were confusing people who downloaded the last release.
Removed dev folder since we have it in the topcoat landing page repo now.
Moving all static files to doc i.e. psds, static css.
The idea being we will generate the style guide into the docs folder just as one would jsdocs.

Need to come up with a final resting place for images and fonts so we aren't duplicating them in the repo.
