1) change in the way how random time scattering in APD is
   generated for optical photons - now the events should be
   reproducible irrespective of whether the random time is
   or is not requested.
2) indroducing a possibility to simulate optical photons, but
   not to process them - this option, however, does not seem
   to speed up the simulation significantly.
