Allow instance admins to add custom CSS that will affect every page of their instance. This is done with a new CustomCSS instance setting that works pretty much exactly like the Users CustomCSS property. This custom CSS is then requested for every page load. User styles/themes take precedence over this CSS. Co-authored-by: tobi <tobi.smethurst@protonmail.com>
