Revert "Don't load admin CSS twice."

This reverts commit 5c44cb03754029204de6a1f4f167950b26d55aea.

This broke admin styling in IE6-8 because the IE specific admin CSS
doesn't include vendor stylesheets for bootstrap, chosen and jquery-ui.
Reverting is a quick fix and we'll investigate the issue properly in
due course.
