style: Add code to make part rules affect the style of the elements.

I still haven't implemented each_part(), so this will do nothing yet.

The cascade order stuff is fishy, I know, and I'll fix in a followup if it's
fine with you. I moved the sorting of the rules to rule_collector, since it
seemed to me it was better that way that duplicating the code, and those
SelectorMap functions only have a single caller anyway.
