TRAC-296: fix(footer) - Respect blog visibility setting in footer nav

Footer "Navigate" section listed every page returned by content.pages
without checking isVisibleInNavigation, so the Blog link always showed
even when Blog visibility was turned off in Control Panel. Fetch
isVisibleInNavigation on each page node and filter hidden pages out
before rendering nav links.

Fixes TRAC-296
