[Impact]
The updated "xfce4-power-manager" and "light-locker-settings" packages resolve a high-importance issue.
LP: #1303736 "Black screen after wakeup from suspending by closing the laptop lid"

 * Users who experience this bug find that their computer is unusable when resuming from suspend. The screen is black and there is no indication of how to restore their session. As a result, the user can only power off the computer, losing their unsaved work.

 * Since this bug causes a loss of work and usability, it is very important that the packages be uploaded quickly.

[Test Case]
This bug affects a large number of laptop users. To reproduce:

 1) Make sure light-locker is running and set to lock on suspend.
 2) Suspend the computer (lid close or the menu)
 3) Resume the computer.
 4) Unlock the user session.

[Regression Potential]
 * There is very low risk of regression. The changes to both applications are only applied when the user changes settings using light-locker-settings. The logind inhibition in xfce4-power-manager only inhibits the lid-close event, and all other events are controlled as they are now.

[Other Info]
 * Affected users will have to restart xfce4-power-manager and light-locker-settings to apply the updated settings. In order to fix the issue...
   1) sudo apt-get install xfce4-power-manager light-locker-settings
   2) Restart session or "killall xfce4-power-manager; xfce4-power-manager"
   3) Use light-locker-settings to toggle the setting.
      a) Disable "Lock on Suspend"
      b) Click "Apply"
      c) Enable "Lock on Suspend"
      d) Click "Apply"
