nicified autobackup (multiple timers in 9libs)

Hello again,

I have made 9libs (or rather libXg) support multiple timers.
It was pretty clean.  This makes my autosave creature sooo
much cleaner, without the horrific global timer to turn off
and on all the time.

If anyone wants to see these patches (multiple timers or new
improved autosave) on the list or in private, just shout.
I don't want to overrun my patch quote to the list.  ;-)
