Added footer, editedheaderwrap to pinpoint error

Problems:
+ Still weird space on the top
+Footer is not centered

What I did:
~h1 and h2 on the top were nested into header tag, I removed it to see
if it was the div tag problem, or with the code I put in the css for the
webkits. I also removed a break after the header_wrap id to see if that
was the problem.
~ added footer tag and styled it to match header.
