Feature request: Setting credentials and port

[cheatfreak47]

Not a complicated request by any stretch, but I would like to be able to customize the port and what login credentials are accepted

Mainly because the current option "empty credentials" still makes the software I use for FTP ask for them every time I do anything, but also because it seems like a good thing to offer if you're gonna have a persistent FTP on a console running in the background.

Would also allow not using any port so programs such as title boot editor work
