DD File Lister: Fix for the "Empty directory" message after quitting (the lister must exit with the number of files listed). Also, updates for filename searching. Also, note ddfilelister is best NOT to be used for the Scan Dirs loadable module option (only for List Files - documentation updated to include this), and the help screen should now always pause at the end. Also, updated DDLightbarMenu to quit its input loop if console.aborted is true.
