Show request details in the result tab

[Yanpas]

Arises from #104

Details should include execution time, query itself, server

The implementation should be different to #104. I mean I don't like to have such details in the tooltip. Also I think the control with the information should allow to copy/paste details. I think may be we need to have a tabbed pane inside output tab ?

I think tabs with tables should have small icon-bar, containing comma button, and show/hide buttons for request infos
