[MERGE] Introducing the Many2Many Email Widget, based on Many2Many Tags. This widget designed for many2many fields on partners checks that partners added in the widget have an email address defined; if not, a popup is opened to enter an email.

The widget is defined in the mail addons module, but this web-side revision adds a trigger when destroying a popup, because this event is used in the widget.
