[IMP] web_editor, *: improve file media widget views & selection

* = web_unsplash, website_blog

Rename "image" to "attachment" when appropriate in FileWidget

Improve image selection / highlight code (now based on attachment id)

Improve image grid view:
 - Remove the row mechanism and replace it by a single loop over the images.
 - Take advantage of row wrap for a responsive display.
 - Uniformize the height (prevent tall images from moving down everything).
 - Load a miniature of the images when possible, remove the loading placeholder.
 	This should significantly reduce the download size when opening the dialog,
 	at the cost of CPU usage on the server.
 - Split the existing image view into one view for the loop and one view for the
 	image itself. This way in a following commit we can reuse the image view
 	when adding a new one, instead of having to render everything again.
