Added username and password to reqired

Need to build as final check nothing broke.

Why would this be desired? librespot works just well in "discovery mode" without giving a username or password.

From what I understood, and found in testing librespot needs a premium account signed into it for it to work. I may be wrong however so will check that this weekend, Thanks for making me check!

@brain0 What version of librespot are you using?

[brain0]

Librespot signs itself in with your credentials as soon as you connect a spotify client to it. A premium account is still required of course, but there is no need to store the credentials on the librespot host. I am using it this way with the official Android and Linux Desktop spotify client.

I am running the latest git master of librespot.

Agree with @brain0. Premium account is required to use "spotify connect", otherwise you cannot use this feature. You can set username and password to librespot if you want to have the device availaible in internet (not in the same network). In my honest opinion there're no reasons to require this information as mandatory.

Thanks for clearing that up @brain0 and @fossedihelm I misunderstood how that aspect of it worked. I may add that to the readme to make it clearer.
