- Replaced BattleSide namespace-enum with enum class - Merged two different BattleSide enum's into one - Merged BattlePerspective enum into BattleSide enum - Changed all places that use integers to represent battle side to use BattleSide enum - Added BattleSideArray convenience wrapper for std::array that is always 2-elements in size and allows access to its elements using BattleSide enum
