Media Grid Attachment Details modal UI improvements:

* Align better visually with the existing media modal and the post image edit modal.
* Add back a link to the full attachment edit screen (post.php).
* Add a title to the modal and move prev/next buttons next to the more-consistent close button.
* Remove mode tabs (metadata vs. image editing) in favor of the Edit Image button.

Still to come: responsive, IE8 testing and targeted CSS (calc() usage), general CSS cleanup.
