DolphinWX: Shut down cleanly on signal

Browse Source 
This makes DolphinWX shut down cleanly, just like it would with
File->Exit when it receives a SIGINT, SIGTERM (Unix) or some signals
on Windows.

The default signal handler will be restored after a first shutdown
signal so a second signal will exit Dolphin forcefully.
