Added CSS lint config (from jQuery).
Fixed CSSlint problems (backup to rgba color).
Altered code to allow for one post type's terms to be updated in the supertags payload. This cuts down on regeneration time.
Learned a lot about the 'save_post' hook and made the code a lot simpler.

Previously, it seemed like WordPress wasn't always using the passed
$id parameter, rather it was using a bunch of crap in the $_POST and
$_GET arrays, but it turns out that's not true. When save_post is
called, you can use get_post($id) to get the fully updated post. So
now I'm passing that $post object to the Gearman worker and it
figures out what to do.
