[Nut-upsdev] instcmd "beeper.off "

Most UPS that I have seen support only "muting" the beeper; I haven't
seen any that allow you to turn off the beeper permanently (although
that is a theoretical possibility provided in the HID powerdevices

Muting is only possible when the beeper is already ringing, and only
lasts until the next alarm condition. 

The renaming you suggest makes sense, but hasn't been done for two
reasons that I can think of:

* backward compatibility (beeper.off has been documented since time
* "off" is a more natural companion to "on".

A good compromise might be to do the renaming you suggest, but also
allow "off" as a synonym to "mute" for devices that don't implement
the "real off" functionality. I.e.:

CMDDESC beeper.on "Enable the UPS beeper"
CMDDESC beeper.mute "Temporarily mute the UPS beeper"
CMDDESC beeper.off "Permanently disable the UPS beeper, if possible, else temporarily mute the UPS beeper"
CMDDESC beeper.toggle "Toggle the UPS beeper"
