Qt: Firewall Rules dialog.

Qt: Firewall Rules dialog.

Add the Firewall ACL Rules dialog. Try showing all valid rules for a
given product instead of making the user select from a combobox.  We can
add the combo back easily enough if that's desired.

Add a rule hint field and use it in the Qt and GTK+ UIs.
