Command line option for version

Not that important but seems a little strange.
I went to try to check the version number in the terminal by using the following command
xfce4-appfinder -v
This did not work, when I looked in help it shows that a capital -V is used, not sure if there is an unknown reason for this. Seems that most applications use a lowercase v for this.

Suggesting to change this option to a lowercase "v" instead.

Thank You
