Jumping to nodes from the debugger to the inspector view

I was stepping through some hit test code and got really deep into the tree... and got disoriented. What node am I handling right now anyway? It would be really useful to be able to jump from the debugger to the inspector view, for example, clicking on a button next to "this" in the variable view, or next to _child, etc. Basically any instance of RenderObject or Element corresponds to a node in the inspector and it would be great for all of them to have a direct link from the debugger to the tree.

Medium priority feature request. This could be a "killer feature" relative to IDE debuggers.

Start with the debugger variable view and inspector view described in the issue, focusing on how RenderObject and Element instances are presented. Define the interaction for linking a variable such as "this" or "_child" to its corresponding inspector node, then verify that the link works for both instance types.
