This should work like the WordPress media modal on the edit post screen. When a user clicks the "Add Whistles" media button, the modal should pop up. Then, they should be able to select from preexisting whistles and groups or create an entire new set.
If we can hook into the actual WP media modal and get rid of the custom button, even better.
It'll probably be a while before I can even attempt something like this, but if anyone wants to take on this project, please do. It'd probably be better to create a separate plugin and unhook what I have now.
