quick frontend(widgets): added QuickWidget.target property as a helper method to get a single target:
a single target is the most common case, but QuickWidget handle multiple targets. When a single target is requested and multiple exist, a random one is returned.
This is a temporary situation, targetting should be improved in a future version to manage multiple targets in hash.
