GIT Support for popups, styles, cached assets

[mwendell]

Describe the feature request

Similar to Advanced Custom Fields, I feel that any professional level plugin should support development environments and GIT storage of changes. I would love to see some way to save my popups, their settings, and even the 'cached assets' in my GIT repo to make deploying them to staging and production servers more seamless.

Use case

We run a large magazine website, and all changes are deployed via GIT. Only code goes out to the server, we never deploy data. It would be amazing if there were a way that Popup Maker could store popups, settings, etc., in JSON files that could be stored in my GIT repo and deployed to the servers.
