Subject: [PATCH] (bug 39957) Added threshold for showing number of page
 watchers.

Added configuation variable that allows bypassing the unwatchedpages
permission when the number of people watching a page is greater
than a certain threshold. The default value is false, meaning the
unwatchedpages permission is always required.
