added static navbar

This contains bootstrap and needed css code. Let me know what you think. 
In addition jquery needs to be added at the bottom of the page. I am not sure how to do that. In my website I just add at the bottom in HTML:     <script src="http://code.jquery.com/jquery-latest.min.js"></script>

Should work fine. Running just the css on my webpage: http://c.albert-thompson.com/xkcd/test2.html
