fixed favicon/ added chewie icon and changed show div

-the favicon was not referenced in the html file so was not showing up, this is fixed
-the favicon is based of logo.png which has been added to the left side of the nav bar as a home button
-the show div has been changed to include the show picture and name text is 1 block instead of a row of picture blocks and then a row of text blocks which is not visually different but will make a php loop later much simpler
