Editorial: update the standard for the WHATWG move

* Update repository files using whatwg/spec-factory.
* Use the WHATWG template.
* Add an Acknowledgments section and IPR statement.
* Sentence-case all headings.
* Add missing example IDs.
* Fix some markup in the introductory example to work well with WHATWG styling.
* Fix some invalid HTML, double-"the" typos, and usage of "and/or" disallowed by the linter.
* Reword some disallowed uses of RFC 2119 keywords, and mark up some uses of "optional" as allowed.

Part of #190. See also whatwg/sg#215.
