rspec_failsafe_formatter

The maven-failsafe-plugin can be used for integration testing. Rspec can be used for integration testing. It would be really cool in the Jruby world if we could easily allow these two systems to communicate with one another. One of the ways can do that is by having Rspec output failsafe xml files. This would allow us to use Rspec for integration tests in Jruby and have our builds exit correctly.
