- CClient now inherits directly from CPrivilegedInfoCallback, like
IGameCallback did before. However CClient no longer needs dummy
implementation of IGameEventCallback
- CGObjectInstance hierarchy now uses CPrivilegedInfoCallback for
callback. Actual events can only be emitted in calls that receive
IGameEventCallback pointer, e.g. heroVisit
- CGameHandler now inherits directly from both CPrivilegedInfoCallback
and IGameEventCallback as it did before via IGameCallback
- 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
