Issue: Navbits Discrepency

If we use a Category to hold our wiki forums, or the wiki forums are not stored at the forum root, then the navbits don't seem to backtrack logically to the wiki root. Instead it uses some combination of forum root/path and wiki root that doesn't make sense. The forum path is not under the wiki root.

Fixed for the next build. The navbits will now only show breadcrumbs that are under the wiki root, rather than under the forum-root-renamed-as-"wiki".
