it is called by Catalyst during setup_components with the application class
as $c and any config entry on the application for this component (for example,
in the case of MyApp::Controller::Foo this would be
-MyApp->config->{'Controller::Foo'}). The arguments are expected to be a
-hashref and are merged with the __PACKAGE__->config hashref before calling
