1) Introduces a new public interface nsIPrintSettingService which emables consumers to create PS objects whithout a nsIWebBrowserPrint interface
2) The implementation is nsPrintOptionsImpl which now impls the private interface nsIPrintOptions and the public iface nsIPrintSettingsService
3) Several methods/attrs have been moved from nsIWebBrowserPrint iface to nsIPrintSettingsService
4) The CIDs for nsIPrintOptions and nsIPrinSettingsService are now the same.
5) There is no longer a CID "@mozilla.org/gfx/printoptions;1"
6) nsIWebBrowserPrint still has the "globalPrintSettings" attr so if you already have an nsIWebBrowserPrint you don't have to create the PS Service to get it.
7) A bug has been filed to rename the imlp of nsPrintOptionsImpl to nsPrintSettingsService.
