/quit now disconnects the window's server without closing anything: every
buffer of that server and wIRC main get a "Disconnected" line, the server card
shows Disconnected with its Connect button, history is flushed to disk, and
there's no auto-reconnect. Connect rejoins the channels we were in (including
ones joined with /join, now tracked) into the still-open windows. Sending while
disconnected shows a "Not connected" line in that window. Exit wIRC still
disconnects everything and closes the app.
