Add Call statistics to Contacts (Phone)

Available from the local menu in the Phone application (except from
the Dialer Fragment).

Call-type filter can be selected in the actionbar.
If all call types are selected the incoming/outgoing rates show up in
blue/green respectively.
Tapping on an item starts a new activity that shows all call types with
details for the given contact or number.
