Notes

++ use an svg for the default avatar
+
++ When we accept a watcher and add it as a contact, it has no display name.
+  We can take it from offline/online presence info instead
++ When a contact is removed and it had "Exchange presence info" enabled, we
+  should remove its uris from the allowed contact list and add them to the
+  blocked contact list (actually check if this is what we want)
++ When "Exchange availability information" is disabled, we still get
+  presence updates until blink is restarted
++ If a uri was blocked then later added to a contact, it will still retain
+  an addressbook policy with policy=blocked, even if "Exchange availability
+  information" is enabled. Despite this, the accounts seem to exchange
+  presence info without problems.
++ Add the ability to merge contacts
