Move Config File

[David Busby]

Please move the config file, like /etc/dsnet/server.json

For when you add featues (inevitable).

I also have the case where I have many configs to use, so in one path by default is handy for me.

I plan to send PR when not on mobile.

I'll keep it where it is for the time being until a need arises.

Note that the project is deliberately limited in scope so there's no plan to add many signifiant more features; though I know someone who's making progress on a web GUI.

Thanks
