Encyclopedia references fixed

A couple of months back I said that the references in the Encyclopedia — which link back to the diary entries on which a person, place, etc was mentioned — were no longer updating. I’ve just finished some work that means these should now be complete and up to date at last! It’ll be a couple more days before I get round to making this happen automatically for new diary entries, but by next week everything should up to date on a daily basis. As ever, let me know if you spot anything that’s broken.
