Changelog:
- 1.46- Mobs only drop rare items when killed by player (drops.min = 0 makes them rare), code tweak, pathfinding no longer sees through walkable nodes
- 1.45- Added Fence Top to add on top of any fence to stop mobs escaping, new line_of_sight tweaked by Astrobe
- 1.44- Added ToolRanks support for swords when attacking mobs
- 1.43- Better 0.4.16 compatibility, added general attack function and settings
