battery.el: Add option to play a sound when battery hits critical?

[T.V Raman]

Subject line almost says it all:

battery.el can change the face used to display battery status in the
modeline. 

Could we also have a defcustom that makes an auditory alert that is
configurable when it transitions from normal to low and low to
critical?

I could do this in emacspeak with an advice, but it might be a more
generally useful feature
