Improvements for directory listing

[MaStr]

Different options are thinkable:

• Make options configurable, config file on USB stick
• Exchange directory listing with LibraryBox version https://github.com/LibraryBox-Dev/LibraryBox-core/blob/master/customization/www_librarybox/dir-generator.php
  • disabled statistics
  • adjust style

We need an update scripte, which removes README.txt and HEADER.txt
