Bob Owen 6c9a5ecfd9 Bug 1156742 Part 10: Allow RemotePrintJob to influence nsPagePrintTimer. r=roc
Adds a new timer for the RemotePrintJob to notify the nsPagePrintTimer when the last page has finished printing in the parent.
Changed the page delay timer to reset the watch dog count on every page to prevent timeouts due to remote printing.
