ui: netstat/events view improvements

- Clicking on a column will display the details of that item (IP,
   process, etc).
   DstIP, DstPort and UserID columns will open the details of the
   selected item.
   Clicking on the PID column will open the process monitor dialog.
   The rest of the columns will open the details of the process.

 - On the Events tab, clicking on the PID column will open the process
   monitor dialog.
