[development] check out nodestack

Hi, Konstantin created a fantastic implementation of my idea about dragging nodes into a block. I would like to see this in Drupal 6 as a generic node select interface. I first though of an API too, but not much an API need with this implementation, just check $_SESSION['nodestack'] . This can be good to select nodes for: -- spam removal -- promoting cool stuff -- node refences and likely a ton of other stuff I can't even imagine but you guys being so cool Drupal developers as you are will do with it. Thanks Konstantin!
