Significantly rewrite the old printing.js:
- define an object PrintUtils that has two "public" methods: PrintUtils.print() to print the content and PrintUtils.showPageSetup() to launch the setup dialog. - global variables gPrintSettings, gPrintSettingsAreGlobal and gSavePrintSettings are removed. These variables were not true cached variables since they were recalculated every time and only used as intermediary.
