Use default cursor when sorting or pagination links are disabled

Hi Alan,

Just a quick CSS update to use the default cursor when sorting or pagination links are disabled:

 18a19,23
 > table.dataTable thead th.sorting_disabled {
 > 	cursor: default;
 > 	*cursor: default;
 > }
 >
 172a178,183
 > .pagination ul > .disabled > a,
 > .pagination ul > .disabled > a:hover,
 > .pagination ul > .disabled > a:focus {
 > 	cursor: default;
 > 	*cursor: default;
 > }

Thank for your amazing work,
