Bug description:
  [Impact]

  In unity-control-center (u-c-c) there is an option for taking an
  action when "Power is critically low".  The choices are "Hibernate" or
  "Power off".  Often Hibernate is a disabled option because of problems
  with hibernate on various systems.

  However - what to do in the event of a critically low power situation
  is now handled by Upowerd automatically and so making a choice in
  u-c-c does nothing at all.

  As such, leaving that option accessible to users will lead to
  confusion.

  This patch removes the option from the UI.

  [Test Case]

  On an unpatched machine with a battery (i.e. laptop) open the power
  panel in u-c-c (Power/Settings menu in the top right corner -> System
  Settings -> Power.  Note that the 2nd option down is "When power is
  critically low".

  Once this update is applied and u-c-c is closed and reopened, this
  option is no longer present.

  [Regression Potential]
  There are some deletions from the ui file and some corresponding code deletions from the associated c file (cc-power-panel.c).

  It is possible that extra code has been removed that could cause a
  crash or affect other options in the power panel.

  However, the changes are fairly small and easy to review.  Nothing
  looks out of place.  Also testing has not shown any problems.
