Fix: Non-English reference pages will not be translated when the lang file is delayed in loading.

Fixes: #1366

Changes:
Added "didReferenceRendered" flag.
Translation is now done correctly regardless of whether the "reference-rendered event" or the "after language file is loaded" event occurs first.
