Uploaded an updated version (0.3-1) in extras-devel

This update does not bring any new functionality. It merely provides a different way to update, copy and delete the configuration options chosen in the gui.
(The previous version was using the command root provided by rootsh)

Cumulative changes:
v:0.3-0
* Removed indirect dependency to the rootsh package (i.e. root command).
* Update in sudoers.
* Added new script to change values.
* Restricted privileges of companion files.
v:0.3-1
* Update in sudoers.
* Improved helper script to copy/delete the configuration files.
* Restricted privileges of companion files.

I've done my best to test and I believe nothing from previous functionality was broken. Nevertheless will wait a few users to test first, before pushing to extras-testing.
