Remove code related to caching articles.  This is no longer an area that seems worth pursuing.  It has generally caused only performance degredation over time.  With improved features such as dynamic filtering as well as investigations into how the ordering of operations affects performance, this may be an area to attack again at some point.  However, for an initial 'release' removing caching seems best.
This change includes a number of feature additions.  It is now possible to both add and delete a feed through the UI.  Also, the UI surrounding adds/deletes has been restyled.  Another major improvement is the addition of URI parsing.  Routes can now be split into the Uri parts and used as such by the Controllers.  Further refinements in the controller layer are required, but will generally provide the desired functionality.
