Subject: [PATCH] Redraw the status bar when a line arrives in another window
 (closes #232)

A line that arrives in a window that is not shown is counted as
unread, but refreshStatusBar did nothing, so the window joined the
status bar's unread list only at the next SetStatus. UI now keeps
the nick, target and connection state last passed to SetStatus, and
refreshStatusBar redraws the status bar with them.

Model: opus-5-5
