Outdated versions will still work.
@version has also been removed.
…sion Forum permissions need to be set for each forum and not for all forums at once. This patch will cause UMIL to automatically default back to a local permission if $auth_option starts with "f_".
Do not replace phpbb_ with the prefix, if it is already at the beginning. Otherwise we would replace the prefix "phpbb_umil" multiple times and end up with phpbb_umilumilumil_tablename, if the constant is not defined.
