Is the plugin "User Shell Script" working ?

[Maik Qualmann]

The user shell script is designed to rework images or change metadata using 
external shell programs.
The BQM assumes that a new file is always created for $OUTPUT. If not, $INPUT 
must first be copied to $OUTPUT and the changes must be made to $OUTPUT.
The $ "variables" are not, they are replaced with real values in the script. 
So $INPUT becomes "/home/use/pictures/tempxxx.jpg" and $OUTPUT becomes "/home/
user/pictures/tempyyy.jpg" as example. The paths are automatically provided 
with quotation marks. In the same way, the other "variables" are replaced with 
real numbers.
