tear-off menu items in submenus of pop-up menus

[Darin Adler <darin eazel com>]

Bonobo is creating tear-off menu items for submenus of pop-ups. There aren't
any tear-offs at the top level of the pop-ups. Michael, do you have any good
ideas on a simple way to fix this? I'd be happy to work on a patch, I just
wanted to see if you had any direction you wanted to give me before I start
looking into it.
