LibGUI: Fixes Widget->set_visible(false) still maintains focus bug

Browse source 
When setting a Widget->set_visible(false), if that Widget->has_focus()
it will continue to have focus, even though it's not visible to the user
anymore.

Now calling Widget->set_visible(false) will remove focus from the Widget
if it had focus, and the Window will give focus back to the Widget
that had it previously, if there was one.
