Add icons to the items in the last section of the front page

I am proposing to add icons beside the items in the last section of the front page. These icons could be from something like the Fontawesome (https://fontawesome.com/?from=io) library.

I created some icons to match up to what was needed per each section of that module. I'll have the design files ready for when Khan gets back.

Will upload the icons in a .zip file as SVG's separately in a moment.
