Smaller jobs, all in one commit!
- Moved object_do_update out of view3d drawing, into
the event system (currently after notifiers).
Depsgraph calls for setting update flags will have to
keep track of each Screen's needs, so a UI showing only
a Sequencer doesn't do objects.
- Added button in "Properties region" in 3D window to set
or disable 4-split, including the 3 options it has.
(lock, box, clip)
- Restored legacy code for UI, to make things work like
bone rename, autocomplete.
- Node editor now shows Curves widgets again
- Bugfix: composite job increased Viewer user id count
- Bugfix: Node editor, not "Enable nodes" still called
a Job, which didn't do anything
- Various code cleaning, unused vars and prototypes.
