#355 Add Crux version number to output files

[William S Noble]

Add Crux version number to XML formats and SQT format.

For tab-delimited, create an option "--output-version T|F" that defaults to F. It will include the version number in the first line, preceded by a #.

Please let Marc Vaudel (marc.vaudel@biomed.uib.no) and Harald Barnes (Harald.Barsnes@uib.no ) know when this is complete.
