remove the "path" var from config before calling App.configure
remove the "path" var from config before calling App.configure

oh, *now* i remember why i removed the magic internal stuff from the
configuration. components have to accept it in their App.configure, or
an ArgumentError will be raised. this is just a hack, for now, but there
should be some way of indicating that a config key/val is internal, and
doesn't need to be passed to the component.
