[Bug 687683] gswin32c : Ctrl+C doesn't stop the application

Note that this fix does not address the issue of whether ghostscript 
should cleanup on exit.  At the moment typing Ctrl+C causes the
process to exit.  This could leave behind ghostscript temporary 
files.  A change to this behaviour would need to apply to several 
platforms, not just Windows.

Log Message:
Fixes bug #687683 "gswin32c : Ctrl+C doesn't stop the application".
Make Ctrl+C in the image window act the same as Ctrl+C in the 
console window, which generates a signal to exit the process.
