Merged changes to DisplaySettings from Stephan Huber in prep for controlling the menu hiding behaviour under OSX.

Browse Source 
Added new WindowSystemInterface::setDisplaySettings() method to provide a mechanism for passing settings onto the WindowSystemInterface so it can then set up the system appropriately.

Added assignment of the DisplaySettings to the WindowSystemInterface in Viewer/ComppsiteViewer::realize().
