Changes to body, and color

Problems:
+ Header tag for the about section causes it to bloat
+ I still don't like how the text shows up, it looks unclear
+ header/footer not centered
+ spacing is awkward

What I've done:
~ removed header tag from the about h2
~ added a bg color to the h1 tags (only one element is using it so it
should be fine) in an attempt to see if i can later add an alpha value
and make it look better
~ re-added auto margin to the body
