Add support for mount RackApp, :at => "/sprockets" with a shorthand of mount Sprockets => "/sprockets".

This is different from the match syntax in that it cannot be used for controller/action and it does not 
assume an anchor at the end of the match. 

For instance, in the above example, if the client asked for "/sprockets/foo.js", the Sprockets app would
have a SCRIPT_NAME of "/sprockets" and PATH_INFO of "/foo.js".
