Doubled the number of monster lairs that rangers will seek out before giving up for the day
Night summary now shows temperature (to better understand when peasants need heating or die of frostbite)
Made a number of changes to handle monster collision issues better
A small number of additional translations
Fixed a small pathfinding error
Fixed a small error in construction assignment for walls
Removed outdated code related to the map editor (code that might have caused false positive exception messages)
Updated Unity engine
Fixed a small library error in the build process
