GWidget: Add a flag to ignore greediness in GWidget::hit_test()

Browse Source 
Normally if a GWidget has the is_greedy_for_hits() flag set, all hit
tests will hit the widget itself instead of its descendants.

Sometimes it may be desirable to override this behavior, and so this
flag now allows you to do that.
