FIX config/filebank_folder must begin with a dot, so the path will be relative to the ZF2 application root path (instead of system path)
FIX config/chmod must be in octal, not in string (because, in this case, it will be cast to int and the result will not be as expected ; see php.net/chmod and php.net/mkdir)
FIX Create module Exception (like all zf2 components : ExceptionInterface + Extends of default Exception)
FIX Generate autoload_classmap
FIX Manager::addKeywordsToFile test $keywords ; before, php sent warning if keywords was null
FIX Send module Exception if mkdir failed
