Adds Entity Translation support to the Search API.

Code

  // we don't provide search integration for the others.

  // entity_language() together with entity_translation returns the current
  // form language of an entity. Hence if the entity is translated the form
  // language usually differs from the main language - what would lead to the
  // removal of a valid tracking language.
