#1085 Improve of help translation files

- Avoid logging an error if a help_{lang}.yml file does not exist in the JAR
- No longer suggest /authme messages for updating the help translation
- Create consistency test to ensure that all help_{lang}.yml files in the JAR have entries for all help sections / messages / default permissions
