Bug fixes

A bug fixed, a few tweaks, and a new feature.

Dev branch of Drupal 6 version.

Added checks if core patched or not.
Messages to user 1 if core is not patched.

A few minor bug fixes. No one reported a problem so I publish these changes because I have another version coming very soon!

First beta release.

Images were missing in beta2 and beta3 because of the incorrect tagging.
