Fix issue with the configurations menu on Mac OS X 

On Mac OS X  due to the Qt use of native  menu widgets the connections
for  a menu  action get  disconnected before  they are  triggered when
using QMenu::aboutToHide()  to remove the items  dynamically.  Changed
to  depopulate  the   sub  menu  just  before   re-population  in  the
QMenu::aboutToShow() event.
