Sort By Key

[karthage-spartacus]

Added the possibility to choose a key for sorting with the flag "-k [key]" or "--key [key]"

Hey!

Thanks for the pull request.

I have to admit that I'm having troubles understanding exactly what this PR does... Could you perhaps post some example input/out when using the "key"option? Or perhaps even better, add some tests :)

Also, if you could rebase on latest master so we can get travis working in this PR that'll be great!

Hi ! well It wasn't very clear indeed...
This PR enables you to choose the key to sort a JSON array. I had an issue with a JSON array which had multiple keys (id int, title string, etc.) and when I used sort-JSON on it, it was sorted by title but I wanted it sorted by id. So I made it up :) . I'll rebase the PR and i'll add some tests in a few days :)

Is this still coming? It's be nice to see, I have a use case where it'd be helpful.
