This has been removed from the upstream library. If we want to progress up to Windsor 5, then usages of this need to be removed.
This is currently used in:
* #irclib `Stwalkerster.IrcClient.Testbot`
* [x] #commandlib `Stwalkerster.Bot.CommandLib.Testbot`
* [x] #helpmebot `Helpmebot`
* #eits `EyeInTheSky`
