Removed the trailing commas that broke Internet Explorer 6-9.

In Internet Explorer, you cannot end an object or array definition with a trailing comma. For example, both of the following lines of code will break IE:

var arr = [ 1, 2, 3, 4, ];

var obj = { a:1, b:2, c:3, };

Note that both arr and obj end with a comma. For more information, see: http://trailingcomma.com/
