Simple operator to force rebuilding of a dupligroup cache.

This is a placeholder for proper depsgraph integration. Eventually frame
changes and some other updates should rebuild dupligroup caches
automatically using the depsgraph. Until then this operator is a quick
way to test the IO from caches and the further drawing and rendering
(TODO).
