IRC Client Library 0.4.0 released!

Version 0.4.0 of the Kitteh IRC Client Library has been released.

This one warrants its own section for breakages.

Breaking Changes

• The ClientBuilder is now Client.Builder.
• CapabilityManager, EventManager, ISupportManager, MessageTagManager, and ServerInfo moved to feature package.
• Renamed IRCFormat to Format and moved to util package.
• By default, exceptions now are now printed to console.
• Staleable now extends Snapshot rather than Actor which probably breaks nobody's code.
• KittehISupportProcessingFailureException was unused, and is thus removed.

Changes

• Fixed rare case of PINGs not being sent, resulting in client reconnect due to no knowledge of server response.
• Fixed a few multi-line Cutter edge cases.
• Improved javadocs and documentation.
• Updated to Netty 4.0.34.
