adds batched output for logging

[stringparser]

Recently I have been reading a lot the bin code and noticed these lines.

• adds lib/batchThese.js
• modifies logging for task_start and task_stop events so the output is batched.

The reason for adding a batched output for task_stop is because sometimes the non-batched output for task_stop would write to stdout before the batch of task_start. I have took a constant length of 4 for the batch instead of 5 because on my 24'' monitor, when I have the terminal window at half the line breaks sometimes.

Very cool!

Haha, nice! I only added it to master, but I can do the same for the 4.0.

@stringparser That would be great - I think as 4.0 gets closer we should quit pushing new features to old versions and focus on that branch.

[stringparser]

@contra done.

I've made a little improvement from this PR to the 4.0 one, details there. Let me know if you want this little twitch in 3.x for the time being or else lets close this one.

By the way, I'm loving how 4.0 looks and feels guys, I really do :)

edit: I've made the changes here equal to those of 4.0

Why not split console.log batching out into a module?

[stringparser]

@contra, after what you left written on #694 I totally understand your point here since I didn't consider 3rd party modules.

I left some thoughts there about how one would do the batching from my perspective.
