- Clear console screen on change to console mode
 - Ensure entire screen is cleared at least once in console mode
   o Was not needed/was done by default, prior to a189bd53
   o Remove GOP clear screen work-around no longer required with this change.
 - These changes improve EnableGop driver in the same way, so update version number
   o Add EnableGop version in UI section, to enable tool builders to track it
