"Styled" runner

[jjoschyy]

Would be nice, if you could add a "styled" runner with more spaces and a bit more color.
For example, just change the following functions in progress.js:

Progress.prototype.onStartClass = function(suite) {
this.suite = suite;
return process.stderr.write("\033[33m\n " + suite + "\n");
};

Progress.prototype.onRunEnd = function(summary) {
process.stderr.write("\n\n");
process.stderr.write(" Time taken: " + summary.time + "\n");
process.stderr.write(" Passed: " + summary.passed + "\n");
return process.stderr.write(" Failed: " + summary.failed + "\n");
};

Thanks,
