Refactored feed reporting, added more debug information, added more error catching.

The bot should hopefully no longer keep reporting the same RSS feed entries when an error occurs inside the loop.
Refactored the various feed checks and parsers to their own methods.
Added '!current rss entries' command for reporting all the rss entries, mostly for debugging.
Added '!todo' factoid.
Added fallback message for RSS feed type.
Changed !current rss entries to !recent $type rss entries so you can specify a specific feed.
Added Project News rss entries support.
Added htdocs => Website project mapping.
