v 0.6 (done)

• DONE

  • Enhance TestSuite / run from command line options
  • TestSuite Tests
  • PVS
  • Killer
  • TT in QS
  • MDP/MPP

• Remarks
  PVS and TT might have some dependencies which I have not fully understood yet.
  Some engines for example only cut with TT values for alpha/beta value in non PV nodes.
  Tests show no drop in Search strength either way and also search tree size shows no
  obvious issues
