acl 6.x-1.1

This is version 1.1 of ACL for Drupal 6.

Version 1.0 has been working very solidly with the exception of a minor glitch when updating from Drupal 5. The reason for releasing 1.1 is to provide a defined base for starting the migration to Drupal 7.

Note: The fix in 1.1 has the potential to produce a harmless warning message (see #694236: Duplicate key name 'nid' query: ALTER TABLE acl_node ADD INDEX nid (nid)). Update directly to 1.2 instead to avoid this message.

Changes since 1.0:
Enhancements:
- Clean up some minor coder issues (no functional changes).
Bugs fixed:
- #680324: Add missing index if upgraded from D5.

Note: The devel_node_access (DNA) 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 and its second block. This is a big help for understanding the forces that control access to any given node.

Note the Drupal core issues listed on the ACL front page, which are outside the scope of ACL. Help resolve these issues to make ACL perform even better!
