Philipp Schafft bcc0e86ca0 Fix: Fixed regression for ICY source client's auth 
This allows ICY source clients to log in again with 2.4.x-style config.
ICY does not provide a username. Therefore the username was unset.
This patch sets the username for ICY source connections and allow them
to be handled as if a username was provided.
Configuration tag <shoutcast-user> was added to select the username to set
to. This defaults to "source".
