This action implements a sensible default end action, which will forward to
the first available view, unless '$c->res->status' is a 3xx code
(redirection, not modified, etc.), 204 (no content), or '$c->res->body' has
already been set. It also allows you to pass 'dump_info=1' to the url in
order to force a debug screen, while in debug mode.

If you have more than one view, you can specify which one to use with the
'default_view' config setting and the 'current_view' and
'current_view_instance' stash keys (see the Catalyst manpage's
'$c->view($name)' method -- this module simply calls '$c->view' with no
argument).
