Invalidate the diff cache if the engine producing the diff changes, or if a configuration setting that controls the diff output changes. This is probably what most users expect, that changing the configuration will result in a change for diffs that may have already been viewed. For wikidiff2 specifically, a change in version or $wgWikiDiff2MovedParagraphDetectionCutoff will invalidate the cache. Refactor engine detection and sanity-checking into a private getEngine() function. As part of this getDiffBodyCacheKey() was deprecated, and subclasses should implement getDiffBodyCacheKeyParams() instead. Drop the deprecated and unused MW_DIFF_VERSION constant while we're at it, and bump DIFF_VERSION since we're already changing the cache key format.
