*) Fixed a problem with saving the lost particles if not all processors have lost particles. \n*) Consolidated Tracker_RK4 and Tracker_LF in ParallelCyclotronTracker. Enclosed in #ifdef for now. Activate by uncommenting #define GENERICTRACKER in ParallelCyclotronTracker.h. \n*) Added the general OPAL OPTION boundpdestroyfreq for Cyclotron Tracker.

A loss LossDataSink is initiated with the constructor, then particles are added (and locally stored).
In the finalize method all data is written to an ASCII or H5 file, depending on the NEW option ASCIIDUMP.

Testing of this is ongoing, there are maybe some gliches, watch out. 

Regressiontest will follow!

@Yianjun: please test the CYCLOTRON related PROBES and STRIPPER element!

fix the mass in *.loss file with more than one plugin element case (open/close the file just before / immediately after data dump)
