moodle/course/category.php
tjhunt 92f008465c admin tree: MDL-10047 and MDL-13104 weird things happen when you turn editing on and off.
That was becuase not enough information was being passed in for the blocks editing controls to construct the right URL to reload the page.

It is also now possible for admin external pages to add some UI next to the turn blocks editing on/off button. For example, when you are editing the list of course catgories, the turn editing off button is now in the right place.
