This makes moving back to the contacts list more comfortable on a phone.

This better conveys the hierarchy of the panels, with the nice bonus of
looking better.

Reduce grid size to 3 for instead of 4, this caused to much space

Reduce margins around grid to the same values as g-c-c and reduce
general spacing

This removes most of the Contact class and makes use of the Individual
of folks directly.
The aim of this refactor is to make the code more readable.
Since Individual provides most of the needed features the Contact class
adds a complicated abstraction without any real benefit.

Transform FakePersona a real Persona which can be used as a placeholder
till folks returns the real Persona.

Use SearchQuery to find the best matching contact when opening
gnome-contacts with a e-mail address
