[Request] Translations Support

[MAGNAT2645]

Would be good to add translations at least to client-side plugin (event names like Map Started, Map Ended, Player Connected, Player Disconnected) as i did here (for example):

public void OnClientConnected(int iClient) {
	if ( !g_cPlayerEvent.BoolValue )
		return;

	char szName[MAX_NAME_LENGTH];
	if ( !GetClientName( iClient, szName, sizeof szName) )
		return;

	char szEvent[128];
	FormatEx( szEvent, sizeof szEvent, "%T", "EVENT_PLAYER_CONNECTED", LANG_SERVER );
	EventMessage( szEvent, szName ).Dispatch();
}

	"EVENT_PLAYER_CONNECTED"
	{
		"en"			"Player Connected"
		"ru"			"К серверу подключается игрок"
	}
