Lots of strings are not translatable

Example: lib\setup\dashboard-templates\* etc

I've excluded the admin facing content from translation. Since they are still subject to change and I'd actually don't want them to be translated. I've considered pulling the "Getting Started" content via the REST API too.. This content will only be seen by the site owner so there's no reason to burden translators with these strings anyway :-)
