Add an "Include image in display" checkbox to the image field

I implemented this. Don't work with existing fields. Needs to remove image field from content type and add again

Thanks for working on this old issue!

Will need test coverage and upgrade path for existing fields.

UI changes should have before/after screenshots added to issue summary.

Got the issue summary started but will need updating

Rerolled for 11.x as #20 failed to apply.
