Feature request: Include the current package version

[darcyabjones]

Hi there!

Thanks again for your great work.
It would be really helpful if the distributed package could please have the current version numbers in them please!

I maintain a pipeline that runs SignalP6 (https://github.com/ccdmb/predector), and i've been getting bug reports from people.
It would be helpful to know exactly which version of signalp 6 is actually installed, so that I know whether to report a new bug to you or ask them to update.

It also helps me to cache pre-computed results, and automatically skip repeated analysis if an identical version has been run before.

Currently the -h --help flag lists usage: SignalP 6.0 Signal peptide prediction tool [-h] --fastafile FASTAFILE.
And setup.py lists version='1.0'.

It would be helpful if you could tag the full version info e.g. 6.0e in these places.
Or a special --version flag is becoming more common.

I use the bump2version to do this automatically with a git tag for me.

I know this is pretty low priority so feel absolutely free to say no.
It would just be helpful.

Thanks and all the best,

Darcy
