Support parsing class graphs in Android dependency visualization

The index page has been forked into class/package versions, which are
identical for now but expected to differ more in the future. Although
there is no way to move between class/package graphs via UI controls as
of yet, it is possible to do so by changing the URL manually (ie., go to
class_index.html instead of package_index.html). The UI control to
generate the current URL also works for class graphs.
