Version: 0.6.3 - Minor Changes

Summery: Fixed addObserver methods which were not functioning as intended when adding multiple functions under the same event. Also added the ability to attach annonymous methods to the observer classes. This can be called with the new AVObj.addAObserver() and Node.addANObserver() methods.

- Added AVObj.addAObserver() which takes an additional argument called method. You can now attach methods directly to the observer system. Removing this event can be called by the normal removeObserver() method.
- Added Node.addANObserver() which takes an additional argument called method. (Same as above but for elements).
- Fixed Major bug which when adding different functions under the same event, that the removeObserver() would not actually remove the observer object.
