Support for image editing & cropping from gallery modal

[roborourke]

Currently you can only edit and image and its crops when uploading or inserting a single image. The expectation is that clicking on an image to edit it when the media modal is in gallery mode will bring up the same image editing interface.

The difficulty here is that there are other image editing properties to consider when in gallery mode including the image captions (separate to the real stored caption) and the image order (you can drag and drop to rearrange them).

When an image is selected we could perhaps provide an edit action that takes users to the image editing interface.

Thank you.

This has been confusing for Fuji TV folks and they asked to fix this. I'll let them know it's on our radar.
