Modifications to eliminate the simulation parameters from

Modifications to eliminate the simulation parameters from
AliITSCalibrationSPD. As a consequence also AliITSresponseSPD can now be
eliminated as previuosly suggested by Francesco.
Henrik has modified the streamer in the AliITSCalibrationSPD in order to make
the code back-compatible with the old OCDB calibration files

- AliITSOnlineCalibrationSPDhandler.cxx
- AliITSOnlineCalibrationSPDhandler.h
here also some minor fixes and mods to eliminate writing of the sim params
in the OCDB files.  (D. Elia)
Obsolete methods removed from AliITSCalibrationSDD and SSD (M.M.)
