TwUI ease of use updates

[avaidyam]

I updated the README a slight bit to what I think TwUI is at: 0.5r1. I've also remodeled the TUINSWindow using the INAppStoreWindow as a base and auto-setup the hierarchy, so as to allow a simple -[TUIWindow setRootView:] call to begin the TUIView hierarchy. It may be required to contact indragiek, for using his window code....

Embedding INAppStoreWindow methods within TUIWindow doesn't seem like a good way to go about it. Just my opinion, anyway.

I agree. I'd love to flesh out TUINSWindow a bit but I'm not sure baking in INAppStoreWindow is the direction we want to go.

It was just a quick example to show something :]

I agree as well, a more functional TUIWindow would be great but I don't know if this is the best way/

Again, just a proof of concept. I can try to rework it to become more compatible and feature-filled WITHOUT using INAppStoreWindow. :]
