Bookmarking URL

When you select Render Graph it should change the URL to .../graph?project=#&rootId=# WITHOUT redirecting.

Then the following cases should work:
If you navigate to /graph?project=#, it should take you to the hierarchy selection
If you navigate to /graph?project=#&rootId, it should take you to the d3 graph visualization with the specified project and root id.

Comment from #139: "We can ... listen to the hashchange event."
