Mike Hearn ca49c5e94d Docs: fix various issues for C4.
- Delete information about hash->signature constraint migration. That
  won't work for C4.0
- Rewrite parts of the api-contract-constraints.rst file to fix grammar
  problems and reduce the weight of the page. Some detail isn't really
  necessary at this point in the docs.
- Mention more things in the upgrade notes.
