Karl Tomlinson 42c19dece3 bug 1227008 use GtkPaperSize in GtkPageSetup directly, instead of maintaining a separate copy r=acomminos
Fixes a leak in nsPrintSettingsGTK::SetGtkPrintSettings() and
missed paper size copy in operator= (bug 965991).

GtkPageSetup always has a GtkPaperSize [1], which is returned from
gtk_page_setup_get_paper_size() as indicated in the docs [2]:
"Return value: the paper size" without "or NULL".
