Add drilldown/drillthrough functionality to KPI based widgets

[Frisle]

To use KPI to its full capacity it needs to have drillthrough. My idea is to send data in array from KPI based widget upon clicking on a row

For example:

Name, review, releases, app published
John, 3, 34, 2

I click on whatever column in this row and front-end send data = ["John", 3, 34, 2]. Then back-end doing its thing and send new sql with data only for this row. New data can be link to John profile and list of all his review or applications than have been published, or only reviews/releases/apps depends on where i chose to click
