(svn r6661) Feature: Windows are not restricted to 32 widget items anymore.
The functions required to do so are to be found in window.h.
Rather then use the old deprecated disabled_state, hidden_state and click_state uint32 variables,
we now need to use accessors like SetWindowWidgetDisabledState, SetWindowWidgetHiddenState or SetWindowWidgetLoweredState.
This is the final commit for the merge of XTDwidget branch.
