Revert "Add shallow routes to the new router" for now. Needs more work.

This reverts commit 67a60ee3.

actionpack/CHANGELOG

 *Rails 3.0.0 [beta 4] (June 8th, 2010)*
 
-* Add shallow routes back to the new router [Diego Carrion]
-
-    resources :posts do
-      shallow do
-        resources :comments
-      end
-    end
-    
-    You can now use comment_path for /comments/1 instead of post_comment_path for /posts/1/comments/1.
-
 * Remove middleware laziness [José Valim]
 
 * Make session stores rely on request.cookie_jar and change set_session semantics to return the cookie value instead of a boolean. [José Valim]
