Delete duplicate images and move images to folder

  -  Remove unused/duplicate images in root directory
  -  Take images that are being used and move them to an images folder
     within the website directory.
  -  Update index.html to point to new images folder
Move FAQ to index, add some more navigation

  -  Move content from FAQ to bottom of index page
  -  Add github mark in header to link to code (ideally this can sit
     alongside other social media buttons)
  -  Add some navigation anchors as targets
  -  Adjust CSS for header box with title
