title: European date input in Django Admin
body: <p>Django has a DATE_FORMAT and a DATE_TIME_FORMAT options that allow us to choose which format to use when viewing dates, but doesn't apparently let me change the input format for the date when editing or adding in the Django Admin.</p>
  
  <p>The default for the admin is: YYYY-MM-DD</p>
  
  <p>But would be awesome to use: DD-MM-YYYY</p>
  
  <p>Is this integrated in any case in i18n?
  Can this be changed without a custom model?</p>
