Show "debug query" information

[GoogleCodeExporter]

Show the "debug query" information of a query when double clicking on a query 
on the query log. 
The information should be well presented.

The same could be done when double clicking on a item on the operations time 
line.
For example if a query takes too much time to identify it easily and show the 
"debug query" information.
