Since passing a CallsContacts pointer down to every class it needs, started to
become laborous - especially since the intermediates classes don't need
the reference themselves - it was made a singleton
* src/calls-contacts.c: Added calls_contacts_get_default () function and
removed calls_contacts_new ()
* src/calls-contacts.h: Added _get_default () prototype and removed the
_new () prototype
* src/calls-application.c: Use calls_contacts_get_default () now
* src/calls-history-box.c: Removed self->contacts completely
* src/calls-history-box.h: Got rid of CallsContacts argument in _new()
* src/calls-main-window.c: Removed self->contacts completely
* src/calls-main-window.h: Got rid of CallsContacts argument in _new()
* src/calls-call-record-row.c: Use calls_contacts_get_default () now
* src/calls-call-record-row.h: Got rid of CallsContacts argument in
_new()
* src/calls-call-holder.c: Use calls_contacts_get_default () now
* src/calls-call-holder.h: Got rid of CallsContacts argument in _new()
* src/calls-call-window.c: Removed self->contacts completely
* src/calls-call-window.h: Got rid of CallsContacts argument in _new()
* src/calls-notifier.c: Use calls_contacts_get_default () now
* src/calls-notifier.h: Got rid of CallsContacts argument in _new()
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.
