Reviewers: BenL, Description: Autogenerated regular expressions required too much whitespace around commas and slashes.
Added support for CSS3 style backgrounds. Will do borders and others in a follow-up CL. Switches to using a regex class for optimization that can differentiate between character set abbreviations and letters when doing head and tail optimizations. Added common substring pooling to the generated JS. With a bit more work in a follow-up CL, this will let us support rgb and rgba colors client side without blowing up the size of the CSS.
