Message:

Addresses #109: Clarify entity / representation / variant terminology

Replace more entity, entities, and entity-body, as appropriate.

Addresses #183: "requested resource" in content-encoding definition

Fixed.

Clarifies #178: Content-MD5 and partial responses

New terminology makes it easier to understand what is digested.
