In the default Space Default View, Pages should show their Summaries, if any

(User Story, Investigate , Priority: High, Test Status: No automated tests yet , Reported By Justin du Coeur, )
Summary: That is, if a Page has a Summary, that should be shown somehow in the default view.
This story is a major motivation for Pages should have the Summary Property.
It isn't obvious how Pages should be displayed. It could be on a line after the Page. It could be on the same line, in smaller type. It could be available as a hover text (will need an affordance to show that there's something there).
