Implements $0, $1, $n

I've finally figured this out.

JSInspectorCallbackWrapper wraps the return value with
JSInspectorCallbackWrapper::wrapOutgoingValue. It wraps it as a
JSInspectorCallbackWrapper, which blocks getProperty, setProperty,
deleteProperty, construct, hasInstance, and getPropertyNames.

I think this is overkill for objects from the "inspected window" but a
necessary security measure for objects from the "inspector".

$0 - Variable containing the most recently inspected object .
$1 - Variable containing the next most recently inspected object .
$n(n) - Returns the nth most recently inspected object that has been inspected.
