*) add 'forward vcard' link to contact actions manu
*) fix bug when a contact with a secondary email address is selected
*) improve support for multiple address books in contact list widget on compose screen
Before the search worked only in Addressbook, not also in Compose.
The point of the change is also to align group searches with contact searches
in that it now uses the same set of attributes. Previously groups
in Compose were searched by name only.
