RemoveRosterMemberFromParty

//RWT-OEI 09/19/05
//This function removes a roster member from the party. By default it
//will remove the NPC from the game world and save them out with their
//current state. If bDespawnNPC is FALSE, then the NPC will not be
//removed from the game world and their state will not be saved.
//Couple with DespawnRosterMember() if you need to remove the roster
//member from the area and save their current state
