Review request for Plasma and KDE Usability.


Repository: plasma-workspace


Description
-------

This adds a new "Inhibition" source which has keys for each application (amarok, vlc, ...) and inside a QVariantMap with the pretty application name (taken from the desktop file through KService and cached locally), the application icon and the reason for the inhibition (as provided by the application)


Diffs
-----

  dataengines/powermanagement/powermanagementengine.cpp 2d370e6 
  dataengines/powermanagement/powermanagementengine.h a06fe7a 

Diff: https://git.reviewboard.kde.org/r/122132/diff/


Testing
-------

Works well, survives plasma reboots, and can now expose this information to the user in the battery monitor.

Adding usability just for feedback on the eventual user representation, see screenshot. It shows the application icon plus either "Amarok has disabled power management: Playing music" or in case of multiple inhibitions "Amarok and n other applications have disabled power management".
