Add Custom Post Type Slugs to Admin Body Class

When in Admin mode, this plug-in adds classes to the tag to let
your CSS know where you are.

For example, if you are viewing the list of all your Posts, you would get this additional class:
edit-list-post
And, when you are editing a Post, something like this:
edit-page-post

Alternatively, for custom posts, for example “movie”, you would see either:
edit-list-movie
or:
edit-page-movie

This allows you to write custom CSS and JS to interact with these varying edit pages within WP.

Please let me know if you have any questions/suggestions/thoughts,
