Port of commit 548519:

Set Singleton=false for the KConfigXT object KVSPrefs.
We can now access the preferences only with DataModel::preferences().
This fixes the syncronisation problems we had with the KVSPrefs, without
the need of KVSPrefs::writeConfig(), KVSPrefs::self()->readConfig()
workarounds, whenever the control flow switches shared library boundaries.
