Add a library to RimWorld.
This mod adds a new room type `Library` to RimWorld.
A closed room with more than 3 bookshelves is considered a library.
Libraries increase the reading speed of characters inside them.
Each additional book in the library provides an extra 5%.
Each additional piece of art provides an extra 10% (regardless of quality).
