setting action buttons on top of nav bar

Of course, any normal biped would put these action buttons in the margin ...

currently the nav bar does hide action buttons which have the same y coordinates.

we have to render them on top of the nav bar not underneath as @gooddosh expects...

pushed new version to https://vc64web.github.io ... should work now as normal bipeds will expect 😄
