try to behave more like traditional tailbone, for the few things
supported so far. taking a conservative approach here for now since
probably other things are more pressing.
still opt-in-only at this point, the traditional tailbone-native
master is used by default.
new wutta master is not feature complete yet. but at least things
seem to render and form posts work okay..
when enabled, this uses a "completely" wutta-based stack for the view,
grid and forms. but the underlying DB is of course rattail, and the
templates are still traditional/tailbone.
