John Layt f3ad57e90e QtPrintSupport - Fix Mac printerName() use
Mac in Qt4 and 5 has been using the PMPrinter Name for the QPrinter
and QPrinterInfo printerName() value, but this is incorrect. This
is in fact the CUPS Description field, is in human readable form
and is not guaranteed to be unique. The CUPS Name field is the
PMPrinter ID value and should be used as the unique identifier
when accessing printers. This has worked up to now due to an
undocumented feature in the OSX api that accepted the Name when
the ID should be used.

Changing all uses of PMPrinterGetName to PMPrinterGetID fixes this
and allows the QPrinterInfo test of names to pass without
munging the names.
