#118675 sorted out access permissions. Also prevented revision tags tab from appearing to users who aren't privileged to see it. Added a feature where the variable revision_tags_unique governs whether a tag must be unique or not. This can be set in , defaults to TRUE.

Initial commit of the revisiontags module. This lets you tag revisions. If a node has more than one tagged and public revision, a block appears that lets you switch between revisions. This would be good for changes in documentation, say on drupal.org, for nodes that cover Drupal 4.6, Drupal 4.7, Drupal 5 and so forth
