Added logic for mapping between ServerEntityIDs and LocalEntityIDs removed old code that wasn't used.

Browse Source 
Added 1 map to Client and renamed m_ServerToClientMap to m_ServerIDToClientID.

// Good to know
To keep this structure please use insertIntoServerClientMaps() when adding items to them.
m_ServerIDToClientID and m_ClientIDToServerID maps between server EntityIDs and local EntityIDs.
To see if a local EntityID exist in m_ClientIDToServerID use clientServerMapsHasEntity(EntityID clientEntityID);
To see if server EntityID exist in m_ServerIDToClientID use serverClientMapsHasEntity(EntityID serverEntityID);
