[NINTENDONT] Send replays to IP/FTP-Server#690

As of now you need to have a PC/Laptop to get .slp files over the network. I would much prefer to send .slp files - for example over ftp - to a machine so you don’t need to manually connect to every console or need to have a PC/Laptop (a Raspbi would be fine then).
In EU we have people buying ~100USB sticks because the current network feature is not scaling well.
