Integration with Addon Packages

[ideadude]

To sell courses with PMPro Courses, you can create multiple levels. You can use the MMPU add on to sell multiple courses.

You should also be able to use the Addon Packages plugin to sell courses. Even when MMPU is in core PMPro, it might be easier/better for some folks to sell through Addon Packages.

So let's make sure Course CPTs show a AP price. And let's make sure that sub pages in general, but specifically with PMPro Courses, are protected if the parent Course hasn't been purchased yet.

This work will mostly be done in the PMPro Addon Packages plugin.
