Add the Avalonia application and the station network
The entry window types contacts and colours them as they are typed; the log, check, bandmap, score and packet windows read the same session. Contacts are shared with the other stations of a multi-operator entry in N1MM's contact message, so an N1MM station on the same network sees them too.
