Added some magic on the road toward more elegant support for dynamic languages

like Groovy and JRuby. Created a DynamicEventDispatcher that automatically maps
attribute, element and set events to methods. Say you have a field:

  public DSet occupantInfo;

you can create a method in any class:

  public void occupantInfoAdded (BodyObject source, OccupantInfo entry);

and then bind that class as a listener using the dynamic event dispatcher:

  _myobj.addListener(new DynamicEventDispatcher(object));

I also created a nicer replacement for the MessageHandler system which is
clunky but still way simpler than using a full InvocationService. Basically we
dispatch MessageEvent as if it were a method call. 

For example, in AtlantiManager I define:

    public void placeTile (BodyObject placer, AtlantiTile tile)

which receives a request by a player to place a tile on their turn. Then in
AtlantiController, I simply call:

   _atlobj.manager.invoke("placeTile", tile);

Of course, in JRuby and Groovy, that's going to look like:

   _atlobj.manager.placeTile(tile);

which is all part of the fun.
