Alex Crichton 5b76a6291e Implement Deref for all imported JS types
This commit implements the first half of [RFC #5] where the `Deref`
trait is implemented for all imported types. The target of `Deref` is
either the first entry of the list of `extends` attribute or `JsValue`.

All examples using `.as_ref()` with various `web-sys` types have been
updated to the more ergonomic deref casts now. Additionally the
`web-sys` generation of the `extends` array has been fixed slightly to
explicitly list implementatoins in the hierarchy order to ensure the
correct target for `Deref` is chosen.

[RFC #5]: https://github.com/rustwasm/rfcs/blob/master/text/005-structural-and-deref.md
