Bug fixes

Stable release for 5.x.

- Sorry for the double release. Two small hitches:
- The form to add the first blueprint generated errors because there was no default value on the bpid parameter, but one was needed
- Another stopgap was added to ensure that the list of current group types is in sync with the lists of bundles.

Several bug fixes and usability changes.

fix problem with tracking recursion depth: when the item being passed was an array it wasn't getting the $depth variable.

Changes since DRUPAL-5--1-0-ALPHA1:

• Now works in PHP CGI, see README.txt for details
• Does not use redirects anymore to improve compatibility
• Now works with page caching enabled
