Subject: [PATCH] This patch allows urls to be of the form
 :module/:controller/:action as well as :controller/:action/:id where :id is
 no entirely numeric by determining if what would be :module corresponds to a
 directory in app/controllers. If it does not then the :controller/:action/:id
 scheme is used.
