Unmaintained [Karll] Unwatch all 1.1.0

This update provides a new feature in the admin CP on the "edit user" page. To access it, click the top-right "Actions" drop-down menu and select "Unwatch All". This will bring up a menu that will allow you to disable or enable email notifications for all watched threads and forums, and also to completely stop the watching of these threads and forums.

This fix prevents the template modification necessary by the add-on from being overwritten by Xenforo upgrades.

This version works with Xenforo 1.2+ only as it's using the new built-in Template Modification system.
