Removed oldforms, validators, and related code:

Browse source 
* Removed `Manipulator`, `AutomaticManipulator`, and related classes.
 * Removed oldforms specific bits from model fields:
   * Removed `validator_list` and `core` arguments from constructors.
   * Removed the methods:
     * `get_manipulator_field_names`
     * `get_manipulator_field_objs`
     * `get_manipulator_fields`
     * `get_manipulator_new_data`
     * `prepare_field_objs_and_params`
     * `get_follow`
   * Renamed `flatten_data` method to `value_to_string` for better alignment with its use by the serialization framework, which was the only remaining code using `flatten_data`.
 * Removed oldforms methods from `django.db.models.Options` class: `get_followed_related_objects`, `get_data_holders`, `get_follow`, and `has_field_type`.
 * Removed oldforms-admin specific options from `django.db.models.fields.related` classes: `num_in_admin`, `min_num_in_admin`, `max_num_in_admin`, `num_extra_on_change`, and `edit_inline`.
 * Serialization framework
   * `Serializer.get_string_value` now calls the model fields' renamed `value_to_string` methods.
   * Removed a special-casing of `models.DateTimeField` in `core.serializers.base.Serializer.get_string_value` that's handled by `django.db.models.fields.DateTimeField.value_to_string`.
 * Removed `django.core.validators`:
   * Moved `ValidationError` exception to `django.core.exceptions`.
   * For the couple places that were using validators, brought over the necessary code to maintain the same functionality.
 * Introduced a SlugField form field for validation and to compliment the SlugField model field (refs #8040).
 * Removed an oldforms-style model creation hack (refs #2160).
