Move several configuration values from Hash to ActiveSupport::XmlMini, which both Hash and Array depends on.
Also, refactored ActiveModel serializers to just use ActiveSupport::XmlMini.to_tag. As consequence, if a serialized attribute is an array or a hash, it's not encoded as yaml, but as a hash or array.
