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.
