Version 1.2.1.0

Remove loop macro from util.h
-This macro causes a lot of problems for Qt.

CASH-Qt: prevent stuck/unusable debug window on exit
-when closing the client with an open debug window, that window could become stuck/unsuable (it was still shown wherea the main window was hidden already)
-fix this by hiding the debug window, when quitting the the client
