In the future the GHNS button might hide itself based on KIOSK restrictions.
Using the GHNS Button will ensure we don't need to manually do this here.

Button currently not yet shown as the category on kde-look is
still missing. This means the code is also completely untested.

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.
