[virt-tools-list] [PATCH 1/2] Add ability to send Secure attention sequence via keyboard



On Windows, the OS doesn't allow applications to handle Ctrl+Alt+Del, because
it's handled by the OS at a much lower level. Although we have a menu item to
send this sequence to the guest, it's not possible to send via the keyboard (in
the windows client). So add an alternative key sequence (defaulting to
Ctrl+Alt+End) to send this sequence to the guest.
