Description Pavel Feldman 2009-09-26 11:25:57 PDT 
- There is no need to track DOM changes while inspector window is hidden. This is different from the way it was working before the dom agent refactoring.
- There is a following bug:
1. Open web inspector for some page
2. Close web inspector
3. Reload the page
4. Open web inspector

Expected: Elements panel showing the DOM tree
Actual: Empty panel

The reason for a bug is that page reload pushes document's representation into the frontend and calls ElementsPanel's refresh. ElementsPanel is trying to be smart and is not processing refreshes while inspector window is hidden. Keeping dom agent operational only while inspector is visible solves both problems.

Note that I needed to restore WebCore::InspectorController::inspectedWindowScriptObjectCleared callback in order to clear injected script properly.
