[UX] Allow 'manage file' from Image Library

Description of the need It would be great to allow users to manage the image files directly from the image library. Currently the manage files functionality is rather rudimentary and buried, but hopefully over time it will get more polish. It is helpful to be able to edit a file and have it update without changing the filename (especially if an image is used on multiple locations and editing it in this way can update all usages at once).

Proposed solution I made a simple concept using the current Image Library view and adding a contextual link that jumps to the manage files page:

It's very rough, especially in the way that it takes you off the content you are editing (so you would lose content, conceivably). But it would be neat if the 'manage file' functionality could pull into the modal window rather than opening at the top level of the window.
