Bad field type reported with entity_metadata_wrapper

Hi,

When I wrap an entity with entity_metadata_wrapper I can get each field type with the type() method. For example:

  $node = node_load(8);
  $entity = entity_metadata_wrapper('node', $node);

  echo $entity->field_subject->type();  // Prints "text"
  echo $entity->field_website_link->type();  // Prints "field_item_link"
  echo $entity->field_date_field->type();  // Prints "date"

But for the email field I get "text". IMHO it's wrong, it must be "email" or something similar, to allow the programmer to distinguish it from the normal text fields.

Regards.
