Build scripts should check for missing entities in translations
If an entity exists in the English DTD, but not in one of the translations, use of that translation will cause a crash (reportedly perhaps a browser crash?)
Therefore, we should have a check in our build script to warn about these kinds of missing translations, so that commits which create new translatable entities will not inadvertently cause such crashes.
