Subject: Refactor the way that the rss module works so that we're not allowing
 the url to dictate arbitrary static method calls.

* Each xxx_rss helper has a single feed() call which takes an id as the argument

* xxx_rss::available_feedS() only returns feeds when they're applicable (ie
  if you're viewing a tag, it won't show you an item feed).

* Feed urls are now in the module/feed_id form so that we can bind a
  feed id to a given module

* Tightened up the Rss_Controller by using url::merge and some other tricks.

* Made the slideshow module express its own feed.
