Optionally force delivery of TUIO pseudo touch events

Browse Source 
TUIO is not a standard "device" as the first application takes
exclusive ownership, this patch makes it deliver the events to the root
window when the app is not focused, allowing for interactive
application development on simulators running on the same desktop.
To force delivery set the environment variable
QT_TUIOTOUCH_DELIVER_WITHOUT_FOCUS to 1
