AliTPCSensorTemp: sensor positions updated according to ALICE-EN-2005-001

  AliTPCSensorTemp: sensor positions updated according to ALICE-EN-2005-001
  AliTPCSensorTempArray: GetSensor method to access sensor by
"TPC coordinates" (i.e. type, side, sector, number)
Interface versions of other GetSensor methods to avoid that these methods
from AliDCSSensorArray get hidden by the overloaded method.

AliTPCcalibDB: updated to include pressure.
                 Dummy copy constructor and operator= to avoid warnings
