Prodigy should advertise its version

Prodigy should define prodigy.__version__ and a prodigy --version command line since we’re all looking forward to a long lifespan for this product. :slight_smile:

Thanks – I thought Prodigy already did this via __version__, but turns out, we didn’t import about.__version__ properly. Just fixed this for the next release! (In the meantime, the version is currently also listed when you run prodigy stats.)
