wishlist 6.x-2.1-beta

This is a general update of the Wishlist module for Drupal 6 compatibility. It adds no new features, but does include a few patches that were incorporated into the Drupal 5 branch of this module which were never given a formal release.

This is a beta. I've given it cursory testing after completing the Drupal 6 conversion steps and all appears to be well, but I am not presently using it production myself. Please report problems to the module's issue queue.
