[TLOZ]: Dark Rooms and Level 8 Logic Fixes (ArchipelagoMW#3222)

Properly name the Book to Book of Magic in Rules.py so you can actually possibly be expected to use Magical Rod plus Book of Magic to get through dark rooms. No wonder we tend to see candles so early oops.

Also adding a rule that you need candles for access to Level 8 so you aren't required to time a Rod+Book shot against a moblin to burn the bush. Might make this a logic trick or something later.
