Created a pretty reporter

This is a simplified reporter from #283 
I agree that the hella long progress bars are ugly. Stretching the progress bar would run into some corner-cases that should be considered in context. For instance, the first-time Intern user writing one test and getting a progress bar with 20 checkmarks is weird. Configuration coming in 3.0 could alleviate some of the aesthetic concerns allowing someone to set a maximum bar width. While we're talking about look and feel, I'm not a fan of displaying all the pass messages while the tests run. I'm much more concerned with failures, deprecated warnings, errors, and (maybe) skips. And what about in-line coverage? Let me think about a few adjustments that could be made now and features that could come with configuration when 3.0 drops.
