Deprecating Gnarails

This release is a convenience release to deprecate Gnarails. You may notice some major under-the-hood improvements, but these were all building towards a goal that is now served better by gnar-cli.

Since we have consolidated, we are archiving this repo and closing up shop.

Thanks for everything, gnarails, and thank you to the devs who built the code and patterns here, whose code still lives on in .gnarrc.
