The base rules that comprise every page (standard tag styling, header

bar, branding area, etc.) are now split out from common.less into

pages/base.less.
A ui/forms.less has been started with some of the standard form styling.
While tearing parts out of common.less, I found two rules,

.new-review-request and #searchbar, which were no longer used. The

former was orphaned when RB 2.0's New Review Request page was written,

and the latter was orphaned with the UI rewrite for RB 1.7.

Tested some pages.
Built an egg.
