Removing build folder.
It was probably always a bad idea to keep the built files around, so let's remove them. You'll need grunt to create browseable files now (next up: upgrade Grunt to 0.4 from 0.3). I'll build for the GitHub Pages version, though.
Adjusted .gitignore
Moved to Grunt 0.4.

Updated README to match.
hey grunt

Who knew you had all these file methods? Guess I don't have to write my
own find/copy routines after all. Oh well.
Huge style updates.
