Fixed the show / hide dialog shortcuts to take the splitter into consideration

Fixed the show / hide dialog shortcuts to take the splitter into consideration,
 So, here's the deal.
 We have a few QSplitters that takes care of helping us with the
 size of a few widgets, they are ok, and we should continue using them
 to manage the visibility of them too. But the way that we did before was to
 widget->hide(); something, and if you hided something using the splitter,
 by holding it's handle and collapsing the widget, then you used the 'ctrl+number'
 shortcut to show it, it whould only show a gray panel.

 This patch makes everything behave using the splitters.
