Title: minify CSS

Minify CSS files by creating a new file, `filename.min.css`, from `filename.css`. Strips whitespace, comments, last semi-colon, and other cleanups [through YUI Compressor](http://developer.yahoo.com/yui/compressor/css.html). Reduces total number of bytes with each request while preserving regular CSS for development and curiosities. Same pattern as WordPress core.

New minified filenames need a change in the referenced file from their enqueued style location. Changed PHP to reference minified files.
