"Unconfigure" script

### Description

During development on this project, it is tough to work on `plugin-templates` because you need a "configured" version of the project to make sure everything builds and works correctly, but then you need an "unconfigured" version so you can add the files to the `plugin-templates` folder.
It would be cool to add a "unconfigure.php" script that undoes everything the configure script does, so it would move your files out of the plugin and back into `plugin-templates`.
I'm not sure how feasible it is, but it doesn't hurt to create the issue.

### Use Case

When a user is developing plugin templates on the project, they can run a script to move their files from the configured state back to the unconfigured state.
