Forked from msgfmt:ui for emergency bugfix

msgfmt:ui

• Adds a full translation UI to your app at /translate
• Can be run locally or in production for crowd-sourced translations.
• Save the mfAll.js into your server dir to sync translations.

Notes

1. If you don't want crowd-sourced translations, use the msgfmt:ui-dev-only package instead, which is a "debugOnly" package that won't be deployed.

2. By default, any logged in user can submit translations. See the SECURITY section in the online docs for how to customize this.
