NSDateFormatters, added a preferredDateFormatter for use when serializing dates to strings, replaced the use of the description method for date encoding to strings with invocation of the preferredDateFormatter, added new attribute transformation strategy from NSDate -> NSString properties (also using the preferred date formatter), and provided customization support for date handling globally and on a per-mapping basis. closes #200, closes #313, closes #309, closes #308
