Go to the dropdown underneath the 'edit' button on each particular page (as far as I'm aware, there's no way to do this to the whole wiki) and click on the 'protect' button. There should be a box underneath the first section which says 'unlcok further protect options' - check that and then change the 'move' section from 'allow all users' to 'Administrators and Content Moderators only'.
