Biographical articles without WP Biography tag

playing around with the query scheme to see what effect things have on performance; a bit slower with the redundant sub-SELECT, but not much. Repeating to see whether there's some sort of schema optimization going on.

Now producing wiki markup so this can be easily cut-and-pasted into WP

Now uses LEFT JOIN so I can deal with both missing talk pages and talk pages missing categories in a single query. Had to make sure query term nesting was got right, as otherwise it selects all articles without talk pages. There is probably a neater way of doing this, but this at least works.

Note that this is far from exhaustive, but adding "X_people" for all X introduces too many false positives.

I've also tried the "People_(associated|educated)_(with|by)..." and "People_from_..." categories, and unfortunately they match groups, so I've removed thrm.
