Subject: [PATCH] Adding possibility to get the Reconstruction parameters from
 OCDB (Marian)

Just temporary fix



  The reconstruction parameters are used in the AliTPCclustererMI and AliTPCtrackerMI

  They are retrieved:
  0. User speciefied it in reconstruction macro
  1. if (not 0) from OCDB  - AliTPCcalibDB::GetRecoParam(eventtype)
  2. if (not 0 or 1) default parameter - High flux enevironment used

  FIXME:
  In the future  reconstruction parameters should be changed on event basis
  But for the moment, event types are still not defined
