Jade Cleanup

[rtoal]

The jade templates should be cleaned up before we do any work on professional styling.

1. In the HTML5 <script> tag, the type attribute defaults to "text/javascript" so type attributes should be removed.
2. In the HTML5 <link> tag, when rel is stylesheet, the type attribute defaults to "text/css" so type attributes should be removed.
3. I see css ids and classnames like button-upper-right and topLeftMargin. Those are SOOO not class names! Do not ever hint at something positional in a class name. Give then semantic names.
4. Note also in item 3 above, am I to assume you went with dashes in names for ids and camel case for classes? Is there a reason for that choice or did you not notice the inconsistency?
5. zombieTest.jade is obsolete and should be removed.
