taxonomy_access 6.x-1.3

The 6.x-1.3 release of Taxonomy Access Control fixes a major bug where editing nodes under certain conditions would corrupt node access records, possibly leading to restricted nodes being accessible. (See #902858: Node records sometimes corrupted after removing all terms from the node and #902858: Node records sometimes corrupted after removing all terms from the node). Various other minor bug fixes and features are also included.

Note: the tac_fields submodule should be considered experimental; do not use this submodule on a production site without thorough testing.
