Added a new create regexp in urls for just scope_path
Now that scope_path is properly defined we can add a url matching
just the scope path. This allows some other custom create regexps to
be removed/rewritten.
Note: It needs to be -after- the full key_name regexp, since for
arbitrarily nested scopes it would always match as just scope_path,
even if there are other fields needed after the scope.
