Made these WeakPtrs to automatically detect if stale pointer is used.

[Evan Stade, 2015/02/24 22:19:22]

not sure I follow, the lifetime of |controller_| and |delegate_| is bound to
|this|. How could delegate() be stale? If delegate_ is null, what does
delegate_->GetWeakPtr() give you?

[bondd, 2015/02/24 23:51:52]

Yep you're right. Fixed.

Comment "The controller owns itself" was wrong; fixed controller_ ownership by
making it a scoped_ptr.
