Reporting tool version, e.g. fc_run.py -v or --version

[peterjc]

As far as I can tell, none of the executable Falcon scripts support a -v or --version command line option to print their version and exit with return code zero.

This is a very common convention, useful in many contexts including larger pipelines where is it important to log the versions of tools used, and automating checking of dependencies.

Could this be added please?

Also, related to this, could the existing -h help option be expanded to report the tool's version?

This would be a less invasive change, although not quite as useful, but you could then do something like:

$ fc_run.py -h | grep version

That's a good idea. We'll do both, eventually. Thanks!
