Formation of the Canon page

For a long time there has been a short section on the NT Gateway on the formation of the canon. Holger Szesnat commented that it was rather tucked away (on the Early Church and Patristics page) and that he had only run across it by accident. So what I've done is to release it up from there and give it its own page: Formation of the Canon. It's a short page so there is plenty of room for expansion. I've also taken Judaica and Early Church and Patristics out from under the "Ancient World" heading on the front page so that they are listed more prominently (NT Gateway: main page).
