Added logo and Community tests

-Per request from Sharpe Engineering, we have added the N-site LLC logo
to the company showcase on the front landing page
-Added images onto the site for me to start testing a new section for
the about page. Once these are on the site, it will be much easier for
me to design a D3 visualization that we will be hosting.
