Monsters list updated

I went through and added a couple of monsters to this list today:

Monsters Encountered So Far

I added greater wights - they've fought them before, not recently, and I'm not sure why they weren't on the list.

I also added the two milk-skinned giants as "Giant, Albino (?)" since they're not sure what they were except that they have white skin.

I'd been meaning to check the list and check it twice, but that's all I noticed that was missing.
