Display when connection is lost and having retry button

Hi!

First, thanks for this wonderful project!

Two things:

1. got disconnected from the IRC server, but I didn't notice it (a friend told me that this stuff was displayed: MyNick (~MyNick@myserver.example.com) has quit (Ping timeout: 265 seconds). I didn't saw anything (neither any error) in the interface, just talking alone for a moment. Ideally, having a icon showing the current connection status will be great!
2. after display this, a cool thing would be a click on a "Retry" button, to restart the connection without losing all the history

Checked the logs, nothing displayed. ~7min after the timeout, got Error: read ECONNRESET in the output.
