When more than 10 columns, sorting icons displays wrong when sorting

Description of problem:
Hello, got this when updating from a really old version of Datatables to the latest (2.0.2 as of the time of writing) on a page with 40+ columns

When there is more than 10 columns and trying to sort on column index 10 and above, the colums with index -10 is showing a highlighted descending arrow aswell awell. The sorting column works and shows the correct asc/desc icon, but also always highlights the desc icon on column index -10.

When sorting is applied on column index 10, column index 0 and 1 will highlight the descending arrow icon.
When sorting is applied on column index 11, column index 1 will highlight the descending arrow icon and so on.

I can recreate the issue out of the box, as my testcase shows.

Hope that someone knows whats up and can fix it, thank you for an awesome product

Funnily enough, this was posted just yesterday as well. I'm going to look at a fix shortly.
