 - [ ] `Client.AddTmpCallback()` for one time use callbacks?
 - [ ] add option to enable PRIVMSG/NOTICE text wrapping (and maybe per-default?) (`Config.DisableResponseWrap`?)
 - [ ] optional flood toggle which uses `EventLimiter` so the user doesn't have to implement it themselves?
-- [ ] allow users to supply a custom `VERSION` for the CTCP reply so they don't have to implement their own CTCP `VERSION` handler?
 - [ ] allow support for proxy URLs (passing to `golang.org/x/net/proxy`?)
 - [ ] allow users to specify a local/bind address using `net.Dialer{}.LocalAddr`
 - [ ] add more generic helpers: `Away()`, `Invite()`, `Kick()`, `Oper()`, generic `Ping()` and `Pong()`, `VHost()`, `Whois()` and `Who()`
