version 1.1.3.beta

things done in version 1.1.3.beta

1. Now DraggableLayer changes the css z-index as well. Thus the dragged layer goes on top of other layers (if possible).
2. Some small nasty bugs have been killed.
3. TreeObject and related objects are partially done. But they are still in development.
4. A new object called TabbedPane has been created.
5. Although the system is in its beta stage, it is quiete stable and it may be used without fear.
