PUBLIC MARKS from svartling with tag chat

I have just made a checkin into the contributions repo of an ajax enabled chat module. This module depends on the buddylist module to allow users to chat in real time with their online buddies on a Drupal powered website. The module includes the drupal.js created by thox for enabling Ajax in Drupal. We started off on this module to explore how we can utilize rich internet technologies like AJAX to create something useful within Drupal. The module is shaping up nicely but it can do with more robustness. This is definitely alpha quality code.
