Trac 0.11-stable doesn't render links to parents

[Martin von Gagern]

Trac-bzr creates revision properties "parent trees" and "changesets". Trac 0.10-stable renders them correctly, but 0.11-stable doesn't by default, as these properties aren't listed among the wiki_properties in the [browser] configuration section.

I guess the proper solution would be implementing our own renderer, maybe generating some nice table with a row for each parent and two colums for tree and changeset.
