Saving ActiveAdmin filters between requests

This shows one technique for preserving filters on index pages for ActiveAdmin resources, without having to patch the ActiveAdmin core.

It restores any previously-used filters whenever the index page is rendered for a resource, unless the current request is an actual application of new filters. It also properly handles the clear-filters button (via a synchronous Ajax request that happens immediately before the normal filter form processing).

Yes, it's a bit of a hack, but it has worked well for me so far.
