Remove some of timeline experiments

LayoutTests/inspector/tracing-test.js

 function initialize_TracingTest()
 {
 
 // FIXME: remove when tracing is out of experimental
 WebInspector.inspectorView.showPanel("timeline");

-    InspectorTest.tracingTimelineModel._startRecordingWithCategories(categoryFilter);
+    InspectorTest.tracingTimelineModel._startRecordingWithCategories("-*,devtools,disabled-by-default-devtools.timeline*");

nit: I think it's about the time to drop bare 'devtools' from the filter.

Good catch. Done!

 
     function onTracingStarted(event)
     {
         InspectorTest.tracingTimelineModel.removeEventListener(WebInspector.TimelineModel.Events.RecordingStarted, onTracingStarted, this);
         InspectorTest.invokePageFunctionAsync(functionName, onPageActionsDone);
     }
 
     function onPageActionsDone()
     {
         InspectorTest.tracingTimelineModel.addEventListener(WebInspector.TimelineModel.Events.RecordingStopped, onTracingComplete, this);
         InspectorTest.tracingTimelineModel.stopRecording();
     }
 
     function onTracingComplete(event)
     {
         InspectorTest.tracingTimelineModel.removeEventListener(WebInspector.TimelineModel.Events.RecordingStopped, onTracingComplete, this);
         callback();
     }
 }
 
 }
