Detect and show AJAX errors on FormXHR submission handling.

Previously we threw away errore reported by the actual AJAX submission and only used whatever error the browser reported to us; this didn't help if we reached the server ok but had a problem there.
We now extract the #error if given and use that in the alert().
Also should now show 'Unknown error' instead of a crappy generic 'something died in jQuery' when we get a 200 response but bogus return data.
