PHP validation scripts written (untested)
Capo controller written and tested

The Capo controller (for XML-RPC server) works. Need to comment the file still. Refactored home controller
(moved part of _build_recent_posts into a recent() method in posts model). Added metadata table to hold the
site's syndication code, name, and plug.
Changed syndication to work properly, and made the syndication page read from the database.
