Title:
  [ffe] Power indicator does not combine multiple battery status

Status in indicator-power:
  Fix Released
Status in indicator-power package in Ubuntu:
  Fix Released

Bug description:
  I have an EliteBook 8540w with internal and external battery running Ubuntu 11.10 (oneiric).
  Linux #### 3.0.0-12-generic #20-Ubuntu SMP Fri Oct 7 14:56:25 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

  The power indicator (indicator-power, version 0.9-0ubuntu2) does not combine the status of both batteries.
  E.g. if one battery still has 1 hour left, and the other has 2 hours left, it will show 1:00 or 2:00, instead of 3:00.
  E.g. When the external battery is almost run out (but the internal one is still charged), the indicator becomes red, instead of staying white/grey. It should only be red when both batteries are almost drained.
  E.g. when the internal one is fully charged, and the external one is discharging, the estimated time show is the estimated time that the external one will be discharged, not taking into account the internal one. see attached screenshot (total time show should be around 4 hours)

  The original applet provided by gnome (I re-enabled the notification
  area) does (still) have the behavior as I expect. In other words, this
  is a regression compared to 10.10 (pre-unity).

  <https://wiki.ubuntu.com/Power#multiple-batteries>: "If a device has
  multiple batteries and uses only one of them at a time, they should be
  presented as separate items inside the battery menu, but everywhere
  else they should be aggregated. Their percentages should be averaged.
  If any are discharging, the aggregated time remaining should be the
  maximum of the times for all those that are discharging, plus the sum
  of the times for all those that are idle. Otherwise, the aggregated
  time remaining should be the the maximum of the times for all those
  that are charging."
