GUI: Fix TabWidget height issues

Changes theme stx files to specify TabWidget's type. That fixes wrong TabWidget height.

Changes TabWidget's getHeight() to return not only "children" height, but also tabs height. That fixes wrong clipping area.

Changes Widget's findWidget to use getHeight(). That fixes bug when widgets in the bottom of TabWidget were not reacting to the mouse events.
