title: localize data annotations default messages ([Required] [StringLength] etc.)
body: <p>if I decorate the properties of my ViewModels with attributes like this:</p>
  
  <pre><code>public class Vm
  {
  
  [Required]
  [StringLength(35)]
  public string Name {get;set;}
  
  }
  </code></pre>
  
  <p>I am going to get english validation messages:</p>
  
  <pre><code>"this field is required"
  "The field Name must be a string with a maximum length of 35"
  </code></pre>
  
  <p>how could I translate them ?</p>
