Somehow I merged out this code. Sigh.
Add notify field to stream.
Timelines are now first class CoreData entities. Timelines have a title, a stream and a predicate.

Filtering posts for notifications now use timelines.

Added a timeline detail view where notifications can be turned on/off.
Better post detail view, debug post's JSON.
Add replies.
Turn own constraint visualisation.
Turn off autolayout for now.
