Rework the telnet window's cluster favourites and login tabs

Favourites show the callsign in bold, the address and the sysop's note,
and each keeps its own password, commands, logon call and note. Clicking
one fills the boxes for editing. Autoconnect marks the favourite to
connect to at start and replaces the old reconnect-to-last-node setting.
A new published list refreshes the notes of the favourites in it. The
published list now spans the window, and the Spot comment tab becomes
Login & Spots with the logon call and keep-alive.
