Subversion 1.6.15 upgrade

In keeping up with the latest Subversion has to offer we have upgraded our SVN cluster to SVN 1.6.15. As a rule of thumb we generally like to wait a few months after a new release before upgrading our servers, unless the release contains critical security fixes. This release brings with it a bunch of bug fixes and improvements. SVN is designed to be backwards compatible, so no need to rush out and upgrade your client, but we always recommend upgrading when possible. Check out the release notes, and change log for more details.
