[driver] Slightly refactored Driver’s handling of OutputMode.

Browse Source 
Instead of having buildActions() call the private Driver::getOutputMode() function, establish an OutputMode using a new Driver::buildOutputMode() function.
This change will allow the OutputMode to be more easily shared across functions without needing to generate it each time (though, at the moment, only buildActions() uses the OutputMode).
