Show the connection state in the neoirc-cli status bar (closes #229)

The status bar has colour tags turned on, so tview read "[connected]"
and "[disconnected]" as colour names and dropped them. It dropped the
bracketed part of a nick such as "erin[away]" the same way.

renderStatusBar now passes the whole status line through tview.Escape,
so every bracket shows as it is. TestStartUp checks that the status
bar shows [disconnected] at start-up. TestStatusBar checks [connected]
with plain nicks and with nicks that hold brackets.

Model: opus-5-5
