Moved Streamer from Utils.h into separate Streamer.cpp

But declared Streamer inside HomeSpan.h instead of separate Streamer.h since it  should only be used when HomeSpan.h is used.

Also, changed class structure so that it is "final" by removing virtual tags and making all protected variables private.
