D6: Use Drupal.behaviors in JS

As per http://drupal.org/node/114774#javascript-behaviors I believe that something needs to be changed near where we use .each.

The upgrade docs give the following example:
Old code:

Drupal.myBehaviorAttach = function () {
  $('.my-class').each(function () {
    // Process...
  });
}

if (Drupal.jsEnabled) {
  $(document).ready(Drupal.myBehaviorAttach);
}

New code:

Drupal.behaviors.myBehavior = function (context) {
  $('.my-class:not(.myBehavior-processed)', context).addClass('myBehavior-processed').each(function () {
    // Process...
  });
};

Committed #8 to HEAD since that part is fine and working. However, project_release.js does use .each(), and it seems like what aclight pointed out in #3 is still applicable.
