Support SIGUSR1/2 for immediate(ish) quit-and-save

Browse source 
Respond to a SIGUSR1 or SIGUSR2 signal by configuring itself
for autosave, saving a new file, or overwriting the current,
respectively, and sending itself a SIGTERM (which _generally_
causes Tux Paint to quit, depending on where you are in the UI).
