commit 4afeb994e1fb9bdef315d0eaa24c3821536e30c1

    call GetAliasFlags() to determine if an alias can be set on a ContactList
    
    Pending FIXMEs:
     - need to lookup RequestableChannelClasses to see if Groups can be
       requested on this connection
     - need to work out the best way to pass ContactListFlags to
       empathy_contact_menu_new()
