Roan Kattouw 1919fffc74 Use serialization cache in MW integration
Add prepareCacheKey() which submits HTML for serialization and saves
the resulting cache key, and tryWithPreparedCacheKey() which uses that
cache key (if available; if pending, it waits for it) for API requests.
Implemented save(), serialize() and showChanges() in terms of
tryWithPreparedCacheKey().

When opening the save dialog, run the conversion, cache it, and fire
off a prepareCacheKey(). Then use the cached conversion for save/diff/
serialize. This means we don't convert multiple times, and it causes
the prepared wikitext to be used.
