This replaces the cumbersome system we had for giving users feedback on settings state changes in the display settings UI. We expect this new system to be what we will attempt to migrate other settings widgets to match over the coming weeks and months. It also provides the opportunity to significant refactor away a lot of the code duplication in settings_display.js. Thanks to Brock Whittaker for redoing the styling and improving the code simplicity. Fixes #7622.
