Remove Version Number from NON-ADMIN pages, so that search engines and others cannot search for a vulnerable revision number.

Now that the application checks for updates, it is not as needed as it once was, and the person who would need to know this information should have access to the ADMIN area anyways.

Thank you for your bug report. This issue has been closed and fixed in Subversion. This change will be available in a future release, but you can download the change at any time from the Subversion server.
