Show generator version when running yo --generators

When running yo --generators it would be helpful to display the version alongside the name of each generator. This could either be the new default or could be selectively enabled with a verbose flag. This would make it much easier to identify the versions of all currently installed generators.

By the looks of this comment, it appears this feature would be a welcome addition.

I think that's a great idea! Would you be interested in sending us a PR?

@SBoudrias Absolutely. This feature requires a change to yeoman-environment so that we have access to the generator version #. If that PR looks good, I can finish up the work in this repo.
