Adding 2 spec formatters, ReRunFriendlyFormatter and ImmediateFeedbackFormatter
Created by: justin808
- re_run_friend_formatter: print copy/paste line to re-run failing tests in one command.
- rspec_immediate_feedback_formatter: prints full description for each test, including time elapsed, and prints error messages immediately.
Please let me know if you like the formatter code. We used this on a big commercial project, and it's all extremely useful. If you don't want this enhancement, I can put this into a separate github repo. If you do want it, I'll add tests like the other formatter specs.
