Wladimir J. van der Laan 9a2305a1b3 qt: Stop shutdown detection timer during shutdown 
Stop the shutdown timer from exiting the main loop
when shutdown is already in progress.

Fixes seeming hanging window after typing 'stop' in debug console.

Also hide the debug console during shutdown as it is useless without
a core to connect to.
