ring my bell

[arnold@skeeve.atl.ga.us (Arnold D. Robbins)]

Matty has the bell code in 9term disabled - you have to define BEEP and you
only get a bell if in Unix mode.

Me, I like to start a long running job and then echo '^G' when I'm done to
tell me I can come back to my system.  So, here's a patch for 9term.c that
makes beeping a button 3 item, independent of the unix/plan 9 keyboard mode.
Not beeping is the default behaviour, so this won't affect you if you don't
want bells anyway.

And hey, if you consider this a trivial patch, don't apply it, but don't
bother to flame me about it. It makes my life easier. :-)
