Description
-------

Currently powerdevil uses the "time-to-empty" property provided by upower to 
add up battery life for all installed batteries. 
Unfortunately, upower 0.9.x does not provide a "time-to-empty" for fully 
charged batteries.
Hence, the remaining battery lifetime displayed by powerdevil considers only 
batteries which are currently being discharged and ignores all fully charged 
batteries.

The proposed patch is taken from upower 0.99.x and sums up the total energy 
available in all installed batteries (discharging and charged) and divides it 
by the current total discharge rate over all batteries (this is for lifetime, 
similarly for charge time).
