We change the code for dealing with contacts quite significantly,
adding a new class, CallsBestMatch, in order to encapsulate a lot of
the functionality that was in CallsCallRecordRow.
At present avatars are not rounded and there are no auto-generated
avatars for contacts with no avatar. This work is awaiting discussion
of Apps_Issues#164.
The CallsBestMatchView and CallsPhoneNumberQuery classes are written
in Vala because they may be generally useful and to leave open the
possibility of adding them to libfolks itself, which is written in
Vala.
