Port to Backdrop CMS

Hi @argiepiano, sorry I have not gotten a response back to you yet on this issue.

Please do go ahead with this. I don't have enough time to maintain both backdrop and drupal, but appreciate that you are able to maintain on GitHub.

Thank you, @mradcliffe!

The module is now fully ported for Backdrop CMS and can be found at https://github.com/backdrop-contrib/agreement

Among the changes, the Backdrop version now stores all settings for agreement types in config json files, which makes them convenient for importing/exporting among sites through Backdrop's core Configuration manager.
