Bug 8597: Create new CCSR theme

Creates a new theme for the OPAC called "ccsr." The new theme has a much
cleaner, more modern look than the prog theme, and is designed from the
ground up to work on mobile devices using media queries. A later patch
will include the mobile view.

In order to activate the theme, change the opacthemes syspref to 'ccsr'
and make sure that your opaccolorstylesheet is set to 'colors.css.'

All work was originally done by Frederick, but I converted his
modifications to the prog template into a new template called ccsr.
