Provide a "reference-with-full-name" syntax for Remarkup

Summary:
Provide a {T123} syntax which pulls in the entire name of an object, not just a
link to it. A major use for this is organizing projects using wiki pages. Since
handle links show object status now, this lets you organize stuff in an ad-hoc
way and get a reasonable overview of it. We can make handles richer in the
future, too.

The performance on this isn't perfect (it adds some potential single gets) but I
think it's okay for now and I don't…
