* REFACTOR: `refreshSort` doesn't cause it to sort again, it's misleading
* FIX: Move queryParams to each discovery controller rather than shared
This fixes issues where params previously would not reset between
routes. For example if you added `max_posts=1` to /latest and then went
to a category.
* Add backward compatibility for (action "changeSort") for themes
* FIX: refreshing was not working
* Update app/assets/javascripts/discourse/app/controllers/discovery/topics.js
