REVISION SUMMARY
  - first check CanControl property, as it overrules things
  - next check each action Can* property, to spare D-Bus call and app activation if false
  - support CanPause and only call PlayPause is possible, otherwise use Play

TEST PLAN
  Vlc can be controlled by keyboard media keys as before,
  Gwenview patched to support MPRIS (with CanPause=false) can now be
  controlled with the Play/Pause media key.
