This PR changes the locations of the status icons shown on file item
thumbnails in the File Browser. Rather than show the file type at the
bottom-left of the thumbnail extent, show it at the item bounds. This
way they always are aligned with each other. This also changes the
current file indicator (top-right) similarly and adds an outline.
