Make Inline examples more "copy pastable"

I think the inline examples on the homepage need to be more copy pastable.  What I mean by that is we are currently misleading newcomers. The first is in the binding example, you definitely need at least 1 line of JS for bindings to work. The next is that all the example refer to an App namespace but we never define it. My solution to this is hacking... you have been warned, but at least the inline examples are more complete.
