Update Notes for Build 0.2.1.3

- Added a few more rooms variations for lairs.
- Added random books spawning to bookshelves in lairs.
- Added item shelves in lairs that spawn with random items.
- Changed crates in lairs to be made of wood so they are colored differently based on wood type. I will soon add a chance for each crate to randomly spawn a wood log on destruction.
- Fixed a bug with the new room lair system that sometimes caused a crash.
