Fix missing Cycles 3D viewport updates when editing materials, lamps.

This introduces a new depsgraph API for getting updated datablocks,
rather than getting it from bpy.data.

* depsgraph.ids_updated gives a list of all datablocks in the depsgraph
  which have been updated.
* depsgraph.id_type_updated('TYPE') is true if any datablock of the given
  type has been added, removed or modified.

More API updates are coming to properly handle multiple depsgraphs and
finer update granularity, but this should make Cycles work again.
