Export to CSV/JSON

[alondahari]

Hi,
Great package.
I think having an option to export the rendered table to CSV/JSON would be greatly useful to a lot of users.
Have you thought of implementing something like that?
Would you be interested in such PR?

A bunch of people have asked for something like this, and this pr is related but never got finished. It's tricky to figure out what options it needs and how to make it available. If you're interested in working on it that would be great, let me know how you'd approach it and we can discuss it first :)

I've run into this on Stack Overflow that covers local downloading to some extent: http://stackoverflow.com/questions/16078544/export-to-csv-using-jquery-and-html

But I haven't had a chance to dig in and tr it out. The code for the actual CSV generation was in the previous pull request, just need to figure out where all the UI should be handled and options for enabling it per instance.
