Inspector: Add a GUI tool for viewing a remote process's CObject graph

Browse source 
Here comes the foundation for a neat remote debugging tool.

Right now, it connects to a remote process's CEventLoop RPC socket and
retreives the remote object graph JSON dump. The remote object graph
is then reconstructed and exposed through a GModel subclass, which is
then displayed in a GTreeView.

It's pretty cool, I think. :^)
