Recently, Valve changed how their CSS classes are named, in doing so making nearly every single theme not work.
CSSLoader now pulls class mappings from an api.deckthemes.com endpoint, and can use these mappings to 'auto-update' themes whenever Valve changes classnames.
Added a toggle in Settings to 'Enable Beta Branch CSS Translations' that will use an API endpoint with up to date class mappings for beta steamos instead of stable steamos.
Removed package-lock.json as it's not needed in a pnpm project.
