Add image name to details view

[springcomet]

When frequently opening multiple images perhaps concurrently on multiple
terminals, it would be convenient to have the image name displayed.

This commit adds the image name to the Image Details view.
Image name is trickled down as an additional string argument

design alternatives discarded:
pass in analysis struct - is not related to analysis
pass new struct with image attributes - premature abstraction

there isn't a lot of real estate in the details pane, but I think this still makes sense to add. Thanks!
