Optionally generate RSpec specs instead of Test::Unit tests

[stevehill1981]

This picks up the configuration from the parent application, so RSpec should be installed and configured before running the generator.

Very much WIP, a lot of work to be done before this is ready.

I also very interested to have rspec tests. This would be a great improvement.

I haven't had any more time to work on this recently, but I'm more than happy to accept contributions to help me get this over the line. We're working against a moving target right now because new features and new Test::Unit tests get added all the time 😀
