configurations. For example, clearing the cache on logout, while using
some kind of persistent store.
Removed Jed from the headless build and instead let `__` call sprintf.
It's now up to downstream users for `@converse/headless` to decide
whether they want i18n support for the few translatable strings in that package
and to implement it themselves.
