dashboard: kill the Qt built-in main window closing mechanism

When the main window is closed, Qt makes QApplication.exec() return, which conflicts with Quamash's implementation of loop.run_until_complete(). The conflict causes Quamash's run_forever() to return earlier than it should, and cause "RuntimeError('Event loop stopped before Future completed.')". Closes #475
