Added Option to also use SILENTKEEPCONFIG

Now the installer and uninstaller can also use the option
SILENTKEEPCONFIG to keep existing configurations.

During install, existing configurations are kept and the new one is
installed as file.NEW.

During uninstall, the existing config files will not be deleted.
