Hi,

The nulls first / nulls last feature was created a few years ago at issue

https://connect.microsoft.com/SQLServer/feedback/details/329337/nulls-ordering-nulls-first-nulls-last-sql-2012

http://stackoverflow.com/questions/5886857/sql-server-order-by-date-and-nulls-last

So, I would like to submit a pul request with SQLServer2008Dialect where the renderOrderByElement method handle this case.

I know that if anyone needs this behavior it can extends the SQLServer2008Dialect class, but It could be provided by core anyway.

So, this change apply? If yes, I only need submit the pull request with tests and issue associated.

Thanks a lot!
