2.5

- Added depsgraph tag for object-change in AnimData, so the
  new animsys doesn't have to all objects anymore.
  (Still WIP, depsgraph has to do this much better)

- Bugfix in notifiers; only 1 notifier was handled for
  frame updates

Result: 2 windows, displaying 2 scenes, now can be edited
independently, and play independent. Not when they share
data, of course. :)
