Add a "quit-requested" signal to the shutdown protocol.

The contact and contact-list editors now demonstrate this part of the
shutdown protocol.  They listen for the "quit-requested" signal from the
shell and prompt to save changes, discard changes or cancel.  If the user
cancels, the editor calls e_shell_cancel_quit() to do just that.
