Replace &JSRef with JSRef in the bulk of the generated code. This will remove a level of indirection throughout all DOM code. This patch doesn't change methods implemented on JSRef<T> to take `self` rather than `&self`, and it leaves a few other uses of &JSRef, but those changes can be made incrementally.
