Bump 29 ports that use GCONF_SCHEMAS. Somehow, the diff of GNOME 2.8.x has
lost the small part. The small part was GCONF_SCHEMAS in bsd.gnome.mk that is
taking care of gconf key and schemas files for pkg-plist. Pav has committed by
re-add GCONF_SCHEMAS back in bsd.gnome.mk this afternoon. Therefore, must bump
PORTREVISION to correct our pkg-plist database installed.
