file mode
fixd dump to file with direct buffer, moved more complex method implementation from .h to .cpp file
added prepareSlave for answering requests
add "done" to result for successful BC+MM messages without other result
implemented answering queries to ebusd, added missing repetition during bs_sendResAck when NAK was received, always log received data in trace level and reduced message length
switch ";" and "," but keep ";" for values shown in/parsed from UI, added todos, removed "p" for poll (use 1-9 instead), formatting
better naming, updated help
