Function RequestCurrentStats no longer exists, so Steamshim launcher does not compile anymore.

	// Note: this call is no longer required as it is managed by the Steam client
	// The game stats and achievements will be synchronized with Steam before
	// the game process begins.
	// virtual bool RequestCurrentStats() = 0;
