User Story

As a content author, I want to see a preview of content that I am about to link to, so that I can determine if it is the correct item.

Acceptance criteria:

• A link field should display a preview or thumbnail of a linked item. It could contain an image, or just some additional useful text.
• A choose dialog should display a preview or thumbnail of a selected item. It could contain an image, or just some additional useful text.
• A choose dialog should display mini thumbnails for all of the items that can be selected if they have images.
• Works with light development.
