Add initial avatar support
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.
