devtools: object inspector toolbar and object stack

This change adds a toolbar to the object inspector with buttons
for inspect (which just links to the same action added to the
context menu) and back. Back uses the newly added object stack
to return to the previously inspected object. Only the objects
which we used the "inspect" command in the object inspector tree
are added to the object stack.
