Module application'

Returns a method that takes one argument and calls the method named prefix+arg,
calling `notfound()` if there isn't one. Example:

    urls = ('/prefs/(.*)', 'prefs')

    class prefs:
        GET = autodelegate('GET_')
        def GET_password(self): pass
        def GET_privacy(self): pass

`GET_password` would get called for `/prefs/password` while `GET_privacy` for 
`GET_privacy` gets called for `/prefs/privacy`.

If a user visits `/prefs/password/change` then `GET_password(self, '/change')`
is called.
