Debug / cheat feature to switch between players in skirmish mode breaks replay CRC

[Caball009]

These are debug / cheat game messages to switch between players in skirmish mode:

GameMessage::MSG_CHEAT_SWITCH_TEAMS
GameMessage::MSG_META_DEMO_SWITCH_TEAMS
GameMessage::MSG_META_DEMO_SWITCH_TEAMS_BETWEEN_CHINA_USA

They change the local player by calling rts::changeLocalPlayer. This causes the replay to mismatch, because MSG_LOGIC_CRC messages are now created with the new local player index instead of the original local player index:

GeneralsGameCode/GeneralsMD/Code/GameEngine/Source/GameLogic/System/GameLogic.cpp

Line 3773 in 45178ee

GameMessage *msg = newInstance(GameMessage)(GameMessage::MSG_LOGIC_CRC);

GeneralsGameCode/Core/GameEngine/Source/Common/MessageStream.cpp

Lines 55 to 57 in 45178ee

	GameMessage::GameMessage( GameMessage::Type type )
	{
	m_playerIndex = ThePlayerList->getLocalPlayer()->getPlayerIndex();

---

AFAICT MSG_LOGIC_CRC messages should always use the original local player index, not whatever it may be changed to. Using the original player index fixes this bug.
