Wiki maintenance

Outward and inward facing wikis synched up. Something odd happened with tracking recent changes, though, on two of them; pages were missing from the list. The restorerecentchanges (a mouthful) maintenance script repaired one wiki, but not the other. Possibly failed because the pages had been touched again, so they didn't show as earlier edits.

Just FYI, none are public wikis. I maintain one as a shop notebook, for instance.
