Add active hook system to settings #1983

After discussion on the above issue I looked and found 3 different places I had monkey-patched a callback system into settings for various reasons. Looking over my own past hacks I think this feature would have made all of them better.

Switching to draft mode until this handles :pushState() and :popState() as well, otherwise it won't be fully functional.
