1) The filling of the root tree was called from musrScintSD.cc, which was
problematic, because no variables were written out if there was no
sensitive volume defined (problem for example when one wants to study
the beam-line properties using just save volumes).
Therefore the tree filling is now called from musrEventAction.cc.
2) A possibility to gently stop the run by creating a file with the
name "RUNNUMBER.stop" in the working directory has been introduced.
("Gently" means that root output file is closed properly.)
