4.30.1

This release cleans up some English strings, and moves us to a new back-end for translation. Now, translations are cached in our CDN which should reduce resource usage and allow clients to properly cache things. Translations are also split into chunks so clients can minimize what they need to request at any given time.

* Fixed: Detection of the subscriber button.
* Fixed: Remove references of non-standard ICU format `en_plural`. Use proper `plural` tags.
* API Added: `i18n.loadChunk(name: string) => Promise<void>` for requiring a new chunk.
* API Fixed: Allow settings to have a `null` i18n key to disable translation.
