[WINSPOOL]
Additional tests show that IsValidDevmodeA/W actually does a lot more than I previously thought. Implement the missing known features and test this little function to death in winspool_apitest to cover each and every possible call. They pass on ReactOS, Windows Server 2003 and Windows 8.1. Credits and many thanks go to Mark Jansen for the additional tests! svn path=/branches/colins-printing-for-freedom/; revision=70595
