- change file save logic to write to a temporary file first, so that we don't
leave an empty/corrupt main file if we crash during saving - started adding Postscript output - renamed "Save as KiCad" to "Write KiCad" - switched from "manual" menu bar creation to GtkItemFactory git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5417 99fdad57-331a-0410-800a-d7fa5415bdb3
