gnome: FormRef and FormError

[Marko Vendelin]

Hi!

this patch adds FormRef and FormError to fine family of the dialogs ported
to Gnome frontend. These dialogs are implemented using an "action" area
to make the work with references as fast and convenient as possible and
scanning error messages less disturbing.
