Dan Peebles 60ecbd7934 More elegant test output
I got sick of trying to find the failures in the sea of debug output, so
we now:
- Hide test output unless it fails
- Sprinkle in some simple color
- Pad results for a more tabular look

If Nix is getting a more friendly user interface, we might as well get
a friendlier developer interface, right? :)
