nautilus: first working version
Improve the nautilus extension to get to a first working version: - Single and multiple selections are working. - The menu item only is there if mat2 has a chance to work on the selected files. - Errors are reported using notifications. Signed-off-by: Antoine Tenart <antoine.tenart@ack.tf>
