core, quick_frontend, primitivus, wix: Contacts List refactoring phase 1:

- QuickContactManagement is not used anymore and will be removed, ContactList + Core are used instead
	- disconnected contacts are now displayed in Primitivus (M-d to show/hide them)
	- avatars are temporary unavailable in wix
	- new bridge method: getContactsFromGroup
