User:Inductiveload/Sandbox/long-s replacements

Some regex replacements that can make a substantial dent in long-s corrections.

This uses the fact that a lot of locations in words will never be "f" (e.g. "fhip"), so we can assume it's an OCR error for a long-s.

This list is empirical, and may very occasionally over-correct (e.g. when a very common word is often mistaken, but the correction could rarely break a correct, but uncommon, word), but the hope it is will still end up with fewer mistakes than before.
