cck_fieldgroup_tabs 6.x-1.0

First stable release for D6. Includes numerous recent fixes and improvements.

If you are upgrading from the dev release, ensure that you first update the Tabs module, http://drupal.org/project/tabs, which is a dependency, to the latest stable release.

The most significant change was #411330: Moving CCK Fielgroup tabs to heavy #pre_render call, which fixes many errors caused by the premature altering of form structures. The module should now be much more stable and less error prone.
