Include line and column information in the JS tracer view

> This is probably better suited in a followup issue, but it would be nice to see the event names as "script:lineno:colno" in the stack based view. Or alternatively, a tooltip over the event will tell you which "script:lineno:colno" event it belongs to. Currently it is not possible to tell which function any of the events are operating on.
