The projects controller gets more RESTy. It now supports XML, RSS, ATOM, HTML and plain text views of the projects list.

Changes include:

 * Add assert_xml_select method for testing RSS and ATOM results (Thanks, Jamis! http://weblog.jamisbuck.org/2007/1/4/assert_xml_select)
 * Add resource_feeder plugin for generating RSS and ATOM feeds
 * Update the URL on the Feeds page to use /projects.rss or /projects.txt instead of FeedController link
 * Add created_at and updated_at timestamps to project table to support ATOM feeds
 * Added new filter to login_system "login_or_feed_token_required" to allow RSS, ATOM or text requests with token-based authentication 
 
Notes:
 * This will break previous project listing feed subscriptions.
 * RSS, ATOM & text feeds are available via session or HTTP_BASIC authentication, or by passing the user's token on the url; HTML and XML results are only available via session or HTTP_BASIC authentication
