Clone, not use link to object when pass it to model

[dmfilipenko]

I found this behaviour when we pass data to model in such way http://jsfiddle.net/4j5ZD/11/ and then change model we are change basic object

I actually wanted this to be how it worked since it will eventually use Object.observe. Then in this case you could do user.name = 'Barry' and it would update both views.

I think it might be best to leave it to the user to clone it if they really want different values. Unless this is presenting some pretty annoying bugs in practice.
