Removed the Turn Lesser Undead tome from Saarthal and instead added a three-line script to the Saarthal Amulet so that it teaches you Turn Lesser Undead when you equip it. This is a more elegant way to do the same job. Again, if you think this is silly, just consider it a present.

A Turn Lesser Undead tome can now be found in the chamber with the first artifact in Saarthal. It's remotely possible to become trapped there indefinitely if you talk your way into the College, haven't slain any dragons, aren't carrying any staffs, and are using a mod that disables starting spells. Okay, so that's pretty astronomically unlikely...just think of it as a present, then.
