* Updated application categories for pie charts to those agreed with Uppsala

* A few visual tweaks
Here is an important thing about JavaScript: There are two kinds of equality operators, one of which is called 'evil twins' in my book "JavaScript: The Good Parts". The operators '==' and '=!' are the evil twins, while '===' and '==!' are the good ones. The evil ones try to do type coercion if the two values compared are of different type, which can give all kinds of bizarre results. Bad!
