This svn update includes several smaller corrections and updates accumulated over last few months: 1) For the Geant4.9.2 it was necessary to remove the privately modified file src/G4EqEMFieldWithSpin.cc. Our corrections in this file (and also in the file src/G4DecayWithSpin.cc) were adopted by the Geant developers into the official Geant code, and therefore these two files were deleted. However, if one uses older version of Geant (i.e. Geant4.9.1 or older), one should rename the G4EqEMFieldWithSpin.cc_for_Geant4.9.1_and_older in his/her src directory to G4EqEMFieldWithSpin.cc to correct for a Geant bug. 2) Implementation of save_polx, save_poly and save_polz variables 3) Implementation of the field map normalisation within the field map itself (was already possible for the field-map formats generated by Toni, now it is extended also for the field maps generated by OPERA). 4) Possibility to swap and invert x and y axis read out from the TURTLE file. 5) Perhaps some other tiny changes
