This does the following:

1) Removes the EnumeratePrinterExtended from nsIPrintOptions and all impls of it
2) Sets the Windows platform to once again use the native print dialog
3) The nsDeviceContextSpecWin will detect at runtime whether to use the standard PRINTDLG or the new PRINTDLGEX (supported by XP and WIN2k), this new code is only compiled in when the ifdef MOZ_REQUIRE_CURRENT_SDK is defined.
4) It adds an extra Property Sheet to the new dialog for Frameset Printing options
5) Now creates a DEVMODE before the diaog is created, this is used for setting different options in the print dialog before it comes up.
