 * Redirects incoming links to the proper URL based on the site url.

 * prevents penalty for duplicate content by redirecting all incoming links to
 * one or the other.
 *
 * Prevents redirection for feeds, trackbacks, searches, and
 * admin URLs. Does not redirect on non-pretty-permalink-supporting IIS 7+,
 * page/post previews, WP admin, Trackbacks, robots.txt, favicon.ico, searches,
 * or on POST requests.
 *
 * Will also attempt to find the correct link when a user enters a URL that does
 * not exist based on exact WordPress query. Will instead try to parse the URL
 * or query in an attempt to figure the correct page to go to.
