Re-implemented this feature in r633365.
Users prior to version 0.8, and developers after today r633365, should have no problems, as the default entity resolver handles it.
Users of 0.8, and developers with older 0.9-dev, who based their sites on 'forrest seed-basic' rather than 'forrest seed-sample' will be affected by
. To workaround that, there is an empty file at main/webapp/symbols-project-v10.ent file.
In any case all users of 0.9+ should ensure that they have a "project symbols" file and take advantage of this sitemap configuration ability. See http://forrest.apache.org/docs/dev/faq.html#sitemap-entities
