REVISION SUMMARY
  Since cmake 3.0 cmake also supports --help-policy-list, matching the
  general --help* pattern. The KDevelop cmake documentation plugin
  already has an entry for "Policies", just it is not filled with any
  content.
  This patch extends the content indexing by also including the policy.
  For cmake < 3.0 the process CMakeCommandsContents::processOutput will
  catch the failing call by the exit code, and things are as before.
