want a way to test out new layouts
specify layout=xxxx in url.
uses builtin layout if available, then looks for card, then defaults to *layout, then hardcoded layout.
tried it and reviewed code. woohoo!
I'm still iffy about requiring layout read permissions for them to work, but that's neither here nor there. Or at least, it's not here.
