Added boundaries to printout

Added newlines and boundaries (lines above, below, and between header and results) to formatted output.
Thanks for spell check! :) I though about boundaries (mysql like), and I have left the out, cause it was always annoying to cut them out from a file to export into excel, etc. But I like what you have done and will add it. Perhaps I will have an export feature (at some point) to save result to a file.
Having said, if it look nicer, let's keep "--", or do we want this to look more like mysql?
