Huge update on version 3.1

Removed DirectoryLister due to the lack of look and feel was out of place and reduced the amount of php addons that was needed. this has the upside that Debian Trixie support is easier.

Directory listing and file listing looks so much better with a preview window now added.

The theme is kept from the main index page for a more cohesive experience.

selecting the file now auto plays, selecting a picture now displays and users can navigate to a music directory and play all music within a folder, kind of like a cheap play list.
