This is a significant rewrite of the built-in Squeak IRC client GUI. A new user interface includes having one console window per connection and then having all console messages, channel messages and private messages contained inside the main console window using tabbed swapped panes.
Numerous other changes are also included but are not described here. The change-set contains documentation for all features added or modified.
