Log:
[LOCALSPL] [SPOOLSV] [WINSPOOL]
- Refactor the code returning PRINTER_INFO_* yet another time to support both EnumPrinters
and GetPrinter calls.
- Implement support for PRINTER_INFO_1 through PRINTER_INFO_9 as well as the mostly
unknown PRINTER_INFO_STRESS (level 0) structure and return as much information as we can.
- Implement GetPrinterW / LocalGetPrinter.

The Printers Shell folder in Explorer now shows our "Dummy Printer on LPT1" and
we pass all 291 winspool:EnumPrinters API tests :)
