Add a "Show all Types" menu item

(Missing Feature, Investigate , Priority: Low, Test Status: No automated tests yet , Reported By Bad Link: Thing 3y284oe not found, )
Summary: Currently, the only way to get to a Type definition is: Show All Properties // click on a Property of that Type // click on the Type link, which requires you to know a Property which makes use of the Type definition you're looking for. [Motiviation: I changed the Name/Display Name of a Model used as the basis for a Model-based Type, and was looking to update the Display Name of the Type itself.]
