Fix annoying error that we have a problem checking for updates if we're simply running an updated version.
- The update checker reports a version conflict if the local version is higher than the version online, but we don't want to release every single subversion (like 3.0-21a, 3.0-21b, 3.0-21c, etc).
- Stop complaining if our root is up to date, but we have a subversion higher.
