V0.23.0

This release is mostly about fixing bugs, but it also features a few prominent changes:

• Cops are now namespace aware, which would it make it simpler to write RuboCop extensions without worrying about name collisions (e.g. you can now have Style/Filename and RSpec/Filename cops).
• There's now logic which prevents auto-corrections from generated invalid Ruby code.
• The Rubocop module was renamed to RuboCop, which will affect packages relying on RuboCop's public API.

Below is the list of all the gory details. Enjoy!
