Idea: Warn integrator if translations not found

[pixelbrackets]

Idea:If the debug mode is enabled, then the script could warn the integrator in case a translation is not found.
Currently, if the title and description keys are empty, because either the language file is not found or the labels are not found in the file, then the affected step of the tour just starts, but shows no window (no next button, no end tour button etc. - the complete modal is missing).
