Title: Add arpa format

Added to_arpa to both ipv4 and ipv6 for ease in converting to longhand to do a reverse lookup. Added tests for this function. I did try to split the classes into separate files but that ended up being more work than it was worth. I also added a Gemfile to install test-unit and shoulda with bundler for ease of use.
