Make grunt test output less noisy

[benjamn]

The JSON format is great for Sauce but not so great for running tests manually in the console.

:ping:, this makes it rather hard to scan the test output quickly when tests fail

[hojberg]

Definitely felt that pain. Could be solved by a summary at the end of the test output and the ability to run 1 test at a time.

Is the new cleaner output good enough? No more raw JSON.

[sophiebits]

Is it possible to reprint the failing test lines at the end? Otherwise I'm happy with the current output.

Going to just close out. I think re-printing could be handy at some point though
