IMPORTANT! The `.qed` configuration file is no longer used for configuration. Either use a unified `Config.rb` file or require a special config file via the `-r` option, e.g. `qed -r ./config/cov.rb`.

Configuration is now handled by the RC library. The only other form of configuration supported is that of requiring a special file directly via `-r ./path/to/file.rb`. This keeps the code as simple as possible without giving-up functionality. Because the old `.qed` configuration file is no longer supported, this release has a major version bump.

Changes:

* Utilize the RC configuration management library.
* Improve hash-arrow assertion notation.
