Add Display for JSON in Table View

[jjnesbitt]

For any given table view, we could have a button on any column containing JSON, which would open a menu that displayed this JSON with a tree-like component. This would have the benefit of greatly reducing the width of the table view (in the case of large JSON blobs), as well as allowing for actual inspection of the JSON data in a meaningful way.

I like this idea. We may need to add a "JSON" column type, though I'm not sure what the implications of that would be.

@jtomeck could do a design mockup for this feature, if and when we decide we want to execute on this.
