nautilus extensions

I noticed that nautilus 2.21 also changes the extension api slightly (the only changes seem to be in nautilus-file-info.h). Also, nautilus looks for extensions in /usr/lib/nautilus/extensions-2.0 now. Packages which install nautilus extensions will at least have to be rebuilt and possibly need some porting. Here is a list of affected packages: nautilus-share eiciel nautilus-python nautilus-actions nautilus-image-converter nautilus-sendto nautilus-flac-converter totem nautilus-cd-burner file-roller evince nautilus-extensions control-center seahorse gnome-mount-nautilus-properties nautilus-search-tool nautilus-open-terminal
