Move stylesheet directory + testing links

I took the liberty to move the 'stylesheets' directory inside
display\body\ into the parent directory. Judging from the 'index.php',
we are pulling the stylesheets in a deeper hierarchy making the workflow
inefficient (and tbh, a bit like a clown show). If there is a grand
reasoning behind this, do let me know... PS. I also added a
'project.php' and 'pageConstruction.css' to test out the images I have
committed earlier. Request to test it out making sure I didnt break
anything.
