Feature request: "You're connected" indicator

[lopcode]

I'm testing Burrow, and noticed that there's no indication that you're connected. I think most servers send you something like "Looking up your hostname" messages which makes it more obvious.

A little message saying you're connected might be helpful. I've attached a screenshot of a successful connection to a testnet, with no messages.

Hmm, this is an interesting one for sure. I think waiting for just a moment and then displaying our own "Connected!" message if none comes from the server would work pretty decently. Kinda wanna keep ircdog relatively light, always printing a Connected! message feels a little strange.

I'll play around with it, might not be that bad once I try it out for realsies. Thanks very much for the suggestion!

If we get readline support (#28), the prompt won't display until we successfully connect to the remote, which will help somewhat.

We might also consider a verbose mode (compare netcat).

for reference, netcat's behaviour:

✨ ~ % nc irc.libera.chat 6667
:cadmium.libera.chat NOTICE * :*** Checking Ident
:cadmium.libera.chat NOTICE * :*** Looking up your hostname...
:cadmium.libera.chat NOTICE * :*** Found your hostname: husky.lolnerd.net
^C
✨ ~ % nc irc.libera.chat 6667 -v
Connection to irc.libera.chat (2001:470:1:dea::95) 6667 port [tcp/ircd] succeeded!
:cadmium.libera.chat NOTICE * :*** Checking Ident
:cadmium.libera.chat NOTICE * :*** Looking up your hostname...
:cadmium.libera.chat NOTICE * :*** Found your hostname: husky.lolnerd.net

Yeah, that's similar to what we print unconditionally in --listen mode:

ircdog/ircdog.go

Line 417 in dd3d41b

log.Printf("** ircdog connected to remote at %s", server.RemoteAddr().String())

I'm sold, let's get a verbose mode.
