Make playback invoked form animation editors more usable

This covers the following workflow. Animator will disable Update All 3D views
in order to get quick playback in a particular 3D editor. However, it also
handy to see playback in all editors and image editors to see comparison of
animation and reference footage.

So the idea here is to refresh reasonable editors when playback is invoked
from animation editors.

Commit to make Hjalti happy.
