Change subject: Put get diff body cache key into own function
......................................................................
Put get diff body cache key into own function
This allows derivative DifferenceEngine classes to
generate cache keys in a different format, as appropriate.
(e.g. for Wikibase, allow diffs to be cached by language
and fully localized)
