  Clean up extensions section

- Resolve inconsistent wording in different parts of the section: fix
places that incorrectly suggested extensions cannot be used with
makeCredential, and resolve conflict between wording that said client
arguments are required vs. not.
- Treat implementations that choose to pass through extensions as a
first-class citizen by requiring that extensions be defined to allow for
this. Fixes #97.
- Fix all the predefined extensions to conform to the updated
guidelines.
- Minor issues: AAGUID should be binary not string (see #61, fixes #51)
and encode true as Boolean in CBOR instead of forcing it to integer
value 1.

  Address feedback from WG review on 6/15 call

- Rename "signature extension" to "authentication extension" (will be
added to glossary in #131)
- Pre-defined extensions recommended (but not required) for
implementation by clients
- Require extensions to update either ClientData or authenticatorData,
update authenticator selection extension to obey this rule
- Clarify that authenticator arguments are sent to the authenticator as
a map, not as bare values
