added print of error codes + more correct error handling of event errors
+ added goto instead of erroneous break to fix bug#7627
provite declarations for signal print functions, needed on some platforms
ome platforms don't like the length calculation for SignalDataPrintFunction
so null terminate instead
ome platforms complain about this extra level Logger::Logger::
null terminate SignalDataPrintFunctions instead
move declaration of print function to SignalData.hpp
just change from "" to <> in include
moved double declatration of i out
