In hcal_calib/hcal_replay_cuts.def:
   add one_clust condition;
   activate good_beta condition (defined for run 52949);
   define 2 versions of the Reconstruct_master cut, one for initial
   calibration and another for iterative calibration.

Remove track related variables from the HMS Shower class, use ntuples
from the track (H.tr) block instead in the HMS calorimeter calibration
scripts.

- Remove a block of duplicated track related variables from the
THcShower class which have been added for calorimeter calibration
purposes.

- In hcal_calib directory, replace those variables with correspondent
variables from H.tr block in the calorimeter calibration class
(THcShowerCalib.h), in the cut (hcal_replay_cuts.def) and output
(output_hcal_replay.def) definitions.
