Refactor News and Marketplace Components Out

Now the News and Marketplace are relying on the same methods to
be rendered out correctly. This allows us to change nav data and have
it dynamically rendered without changing any code.

But now I'm having problems with CollapsibleGroup accordion on small
and medium and closing collapsibles when the menu closes in small.

Removes unused marketplace and news components. There is no reason
the rendering logic should be different between the two.

Audits require statements to remove unused dependencies and mixins.
