Fix "show hidden files" issues

Use KFileItemModel instead of KDirLister for toggling the whether
hidden files should be shown. This assures that the signal
KFileItemModel::loadingCompleted() will be emitted.

In the longterm Dolphin should only use the KFileItemModel, so that
the KDirLister instance is used only internally as implementation
detail in KFileItemModel. Although there are only a few cases left
where KDirLister is used instead of KFileItemModel this cleanup
will be postponed to after the 4.8 release...
