Fabio Alessandrelli bf9aae09ba [Net] Move multiplayer to core subdir, split RPCManager.
Move multiplayer classes to "core/multiplayer" subdir.

Move the RPCConfig and enums (TransferMode, RPCMode) to a separate
file (multiplayer.h), and bind them to the global namespace.

Move the RPC handling code to its own class (RPCManager).

Renames "get_rpc_sender_id" to "get_remote_sender_id".
