List view is replaced by KPluginSelector. This is not an optimal
solution as it makes it impossible to get the selected item and
reloading seems also not to work after a new script is installed.
This should become a proper Model based view.
This KCM has been implemented by Tamas Krutk in the scope of
Google Code-In.
It is a simple KCM just listing all available scripts and allowing
to import/export them.
This will be further extended alongside the planned scripting changes
in 4.9.
