active_class attribute on NavLink has stopped working in latest lap

[catmando]

works fine on page load, but not after that...

experimenting with this a little demonstrates that the there is no reactive update going on.

for example adding this on(:click) handler works around the problem

NavLink("/#{path}", active_class: :selected) { path.camelize }.on(:click) { force_update! } 

This means the problem must be around NavLink or the containing component is not getting a reactive update.

This could be because of other changes made in hyper-react during 1.0.0.lap development

actually this is a problem with react-router 4.x see https://stackoverflow.com/questions/43895805/react-router-4-does-not-update-view-on-link-but-does-on-refresh

hyperloop implements should_component_update which breaks react router.

Solution is to add a global state variable so we can react when the location changes.
