around it.

release notes: removed that ugly orange color from links

Now it is a nice blue color, while visited links are dark gray. Also
all links don't have decoration until hovering the cursor over, which
causes it to become underlined.

The Creative Commons license styling on the footer is ugly. This change
alters the HTML slightly and centers the text.
