Issue #36: Moved and adjusted the featured student block as necessary

- The featured students are now in the main content section.
- I installed the 'contrib/empty_front_page' module to enable the front
  page to not need content. This will need a correction in all the DBs,
  the default front page needs to be changed from 'frontpage' to '' at
  admin/config/system/site-information
