sortFunction doesn't work for DataTable

[berdyshev]

I'm submitting a ... (check one with "x")

[x] bug report
[ ] feature request
[ ] support request => Please do not submit support request here, instead see http://forum.primefaces.org/viewforum.php?f=57

Current behavior
Documentation says that Column has sortFunction property, which can be used for custom sorting. But this callback is never called and I don't see even it in source code of the DataTable component.

Expected behavior
Ability to define custom sorting for the column

Will be fixed in next week's 1.5.1.
