- changed track storage to AliHLTGlobalBarrelTrack

- changed track storage to AliHLTGlobalBarrelTrack
- switched to the AliExternalTrackParam function for the calculation of cluster residuals (cluster errors need to be updated)
- implemented reconfigurable arguments:
  -event-modulo 20 (default), for the number of events which the track multiplity should be averaged over
  -buffer-size 5000(default), for the maximum number of entries for the ntuples filled (circular buffer approach)
- implemented functions for the reconfiguration from the OCDB entry
- removed obsolete or unnecessary functions
- removed dE/dx plot, will be produced by another HLT component
