Nut upsdev - Nov 2009 - RFC: adding a new variable battery.runtime.elapsed

guys,

a very special integration case needed a new variable to exposed the
time elapsed on battery.
I do know that it could have been computed by a upsmon like client
application, but it was not possible in this specific case.
so we went the firmware way to implement the logic, to minimize the
impact on NUT, requiring only the creation of a variable for the
mapping.

I thus propose the following new variable:

battery.runtime.elapsed: Elapsed battery runtime (seconds)

Comments?
