New version - no ajax loading of links

Hi!

I've been using this refurbished version for some time now and I thought that maybe you'd want to merge it.

It currently doesn't need to make an ajax request per file, as we have it already in a Download link on the list view.

Also, I'm not trying to filter files depending on their type.

This code creates a textarea below the list with the urls ready to be copied and pasted into JDownloader.
