gnome: add contacts treeview
Added dependency on libebook1.2-dev in order to fetch
contacts using evolution-data-server.
Contacts from enabled addressbooks are shown in contacts
tree view with photos (if available). The same image is
also shown in the call views.
Double clicking on a contact method should call that
contact.
