Cairngorm + Modules

There are a few notes to take care:

1) For Singleton Class like DragManager which holds data, it is better to put in ApplicationDomain as RSL.

2) While using Modules, the modulesInfo needs a differnet ID even the class is the same, i.e. new another ModuleInfo even the source is the same.

3) The "Modular" Package is adopted.

For now I didn't get ServiceLocator to work as I want. Will think of adopting the Prana framework anyway. We'll see.
