Integrate home page with refinery

1. Figure out why header is not appearing in Mayra's home page template.
2. Pass any localization strings to the refinery home page template.
3. Simplify number of page parts. There shouldn't be a separate page part for each "title" and "description" and "image"
4. Integrate student passions and fields of study into refinery home page template.
5. Make the home page template load instead of the static HTML. remove static HTML once the refinery template is complete.
