port: gnome_window_icon_set_default_from_file to gtk_window_set_default_icon
port: gnome_about_new to  gtk_show_about_dialog
cleanup: remove configure generated files
typo: in .spec file
fix: autotools files (mostly, I think) so that everything actually installs to --prefix (DESTDIR= still does not work)
port: from gnome_help_display to gtk_show_uri (requires gvfs)
fix: install locations for previous commit
fix: look for the window icon inside --prefix
