Subject: * Made a quickupdate method to run through only entities that have
 scheduled themselves for updates looking for changes.  This runs 10 times a
 second. * Set the massively slow UpdateEntities method to run every 2 seconds
 instead of 10 times a second.  This method runs through *all* of the entities
 can calls the virtual update(). * Documented some of the code in the
 scene.Update method.
