Enhancement: Add json output & elasticsearch

We were wondering if you have got any plans to add json output. It would be cool to have more information on the owner. You could put some owner information like owner's nickname, email, location, company. Most of the time that information is not available but it's better to have them.

If we have that information, it's quite easy to disclose private information. It would also be nice to index the findings on elasticsearch. In order to generate some cool graphs.
