Draft: Add symlink info in thumbnail view

Making this a draft because I'm not totally sure on the look/solution to this. Please let me know what you think!

Fixes issue where symlink icon would not show on files with thumbnails.

Adding a symlink icon to the image thumbnail would be confusing visually (is it part of the image?), and defeat the purpose of the thumbnailer which is to use an already existing thumbnail.

The solution here is to add a Symlink column when using Thumbnail search. I added symlink info to the details and tried to make the details a little more organized.
