Feature/setroot

[FigBug]

Add Inspector::setRoot so the component that is being inspected can change. Optionally, the component being inspected can be whatever top level juce component is under the mouse.

Trying this out locally, I triggered an assert on inspector_component:194

jassert (selectComponentCallback);

and then pushing through that, things crashed in MessageManager::runDispatchLoop()

It seems like setRoot (which calls ensureTreeIsConstructed) is being called before the callbacks are setup.

It happens when i click my button to construct:

            inspector = std::make_unique<melatonin::Inspector> (*this);
            inspector->onClose = [this]() { inspector.reset(); };

Looks like bool inspectorEnabled is never initialized. So this error occurs if it is randomly initialized to 'true'. Setting it to false resolves the issue.
