In AliMUONTrackReconstructorK:
  - Correct computation of local chi2 at first cluster.
In AliMUONQADataMakerRec:
  - change computation of local chi2 (X,Y) at cluster.
  - add histo of local chi2 (~0.5*(chi2_X+chi2_Y)) at cluster (this is what
    is used to select clusters during the track improvement at the end of
    the tracking procedure).
  - add histo of ThetaX and ThetaY angles of the reconstructed track (not
    corrected for MCS in absorber)
  - move summary histograms in the no-expert list
