Review request for Plasma.


Summary
-------

This patch introduces API to allow a DataEngine to force an update from sources out to all the connected visualizations regardless of their update intervals.

The use cases for this are things like the time engine or when an engine goes from being offline to online and wants to prompt an immediate update.
