function uuidreference_form_alter in UUID reference field 7

Implements hook_form_FORM_ID_alter().

Alter the field_ui_settings_form to add in the correct bundle options via AJAX. This cannot be done in uuidreference_field_settings_form() as we don't have access to the whole form or form_state. We also have to account for the field settings form, and field settings edit form.
