Separated proposed changes to extension semantics from PR #386 and use TypeError, per @jyasskin

Per discussions on the 22-Mar-18 WG call, these semantic changes previously part of the mbj-registries-and-extensions branch proposed as pull request #386<https://github.com/w3c/webauthn/pull/386> are now in the separate branch mbj-extension-semantics. Thanks to @jyasskin<https://github.com/jyasskin> for suggesting the use of the TypeError exception.

See pull request https://github.com/w3c/webauthn/pull/389.
