Replace the Networked stations window with Options tab fields

Station Number, Port and Version to claim are now on the Options tab of
Network Status and save when a box loses focus. The other settings
(station name, listen port, peers, link on/off) are in a Stations
Configuration window opened from a button on the same tab. The explanation
texts and the Config menu item are removed.
