extension and converts it if necessary. As this check is case sensitive,
processing .JPG files does not work.

Fixes #47.

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.
