Improve file addition when creating tours

[castilhovirginia]

When creating tours, the images of the files are not appearing.

And also, I have a suggestion: for files addition, show the files by taxa and not by the media title.

Fixed the broken images for tour images in a393779, but the images of the entries to be loaded are still broken.

I don't think it's possible to show files by taxa, but it's possible to add the taxa of a file in the details. And it's also possible for the search to search all the media details, including taxa (currently it's just searching the title).
