CC-3220: Stream Setting: Status box is stuck on waiting if nothing is

changed and click save

- done
- liquidsoap_update_error and liquidsoap_update_connection functions are
combined into one function, liquidsoap_update_status, in various place
- created various telnet commands in liquidsoap( connection check for each
stream, connection status for all streams)
- In liquidsoap, shoutcast stream doesn't use default id. It is more
informative by using id with "shoutcast_stream_#{stream_number}
