Re #180: Add multiple mutex groups
* Add multiple mutex groups to UnitEquipmentItem
* Add new attribute to Race schema
* Make everywhere handle multiple groups instead of assuming one
* Make factory load new attribute then fall back to old (deprecated) attribute
* Add method to Unit to get the blocking items (useful for future UI work to say "replace X and Y with Z")
* Add IsMutuallyExclusive method to UnitEquipmentItem to determine whether mutex groups overlap
