Subject: [PATCH] (not part of build) Add notion of CanHandleContent. This is
 supposed to be a light weight method for the implementor such that the uri
 loader can ask right off the top if the listener can handle a particular
 content type. If it can, then later on, the uir loader may call DoContent to
 actually handle it.
