hierarchical_select 5.x-3.0-beta2

Changes since DRUPAL-5--3-0-BETA1:

• Fixed #276268: Missing require_once calls for common.inc
• Fixed typo in the JS which caused the animations and callbacks to fail.
• Updated the subscriptions_taxonomy FAPI code to use the new #config property.
• #277044: Clarify that a vocabulary's "Multiple select" setting is managed by the HS config
• Fixed #276328: Node preview functionality stops working
• Major improvement when JS is disabled: only a small part of the help text is displayed, on hover you will get to see more. This relatively advanced CSS doesn't work in IE 6, but it works in IE 7 and the other (decent) browsers.
• Prevent form altering when an exposed filter is being removed.
• Fixed #276221: Content Taxonomy Views not working: root level is always empty
• Fixed #276142: "Save options" and "Multiple values" not managed by HS upon creation of new field
• Fixed #276347: HS Content Taxonomy doesn't work when no root term is specified
• #277780: Support for the 'both' and 'cck' "Save options" of Content Taxonomy fields
• Minor addition to the _item_get_label() hook documentation.
• Hierarchical Select is now also used on the form to add/edit terms!
• Automatically set save_lineage = 0 when it's the forum navigation vocabulary!
• Updated the README: listed all other core modules with which we now integrate. I also was able to remove one of the troubleshooting entries thanks to the changes of the last commit.
