This is hidden behind the FUTURE flag, and is not ready for release yet, but is pretty usable. The three top filters (all/people/rooms) aren't plumbed in yet, recents need to be reinstated, and a favourites system would be very desirable. The code for the existing roster/chatlist is largely unchanged and with FUTURE disabled behaviour should not have changed. Lots of this code has now been put inside #ifndef NOT_YET blocks, to make it easy to find and remove later. When making this default later, all instances of NOT_YET should be inspected, unit tests should be added, and use of RECENT should be inspected - those related to this patch should be removed. Not all code is behind NOT_YET, so references to the old recents and chat lists will need to be manually checked and removed. Test-Information: Existing unit tests pass. New unit tests have not been added yet, and need to be before it's removed from FUTURE guards. Firing up Swift with future enabled shows the new view, and disabled doesn't. In both cases clicking around various things in the rosters opens the expected chats. Change-Id: I0e1ce98e4c644fa5b09ef65986cc826b6b564a7b
