Gnarly Frontend Page Sort

Gives user the ability to order sub-pages on the parent page from the frontend of WordPress.

There are some backend plugins that do this, but I recently had a project that had about 30 parent pages, and those had sub-pages, and the sub-pages had sub-pages. We needed to find an alternative solution on the frontend because the majority of the plugins were drag and drop on the admin screen. This fixed this problem.
