Improve launcher command line interface.

[ThatRedox]

• Rewrite the launcher CLI using Apache Commons CLI.
• Improve launcher interactive setup.
• Setup unit tests for the launcher.

This does slightly change the usage of the CLI. The new parser parses all command line arguments until -- for the launcher. Any arguments after -- will be passed to Chunky. Any unknown commands will return with Unrecognized option: -<command>.
