acl 6.x-1.0-beta4

This is BETA4 of ACL for Drupal 6.

We do not recommend installing it on a production site, but we encourage you to test it and provide feedback (both good and bad!) in the issues queue. See #322279: ACL for D6 Released for details.

Changes since BETA3:
Enhancements:
- Factor out form code into .inc file.
- Enable grant priority.
- Add new acl_get_uids() function.

This is the first version with working grant priorities, and by factoring out form code, it has become much lighter. This version is required for the new Forum Access and Image Gallery Access versions!

Note: The devel_node_access module, which is part of the Devel module, provides an in-depth view into the inner workings of node access, especially if you enable its debug mode at admin/settings/devel#edit-devel-node-access-debug-mode . This is a big help for understanding the forces that are controlling access to any given node.

Note the Drupal core issues listed on the ACL front page.
