Deprecated deferred.pipe

[rahulthewall]

It's me again, there's more deprecated code in parsley.js that should be removed.

JQMIGRATE: deferred.pipe() is deprecated

Here's the deprecation notice

Deprecation Notice: As of jQuery 1.8, the deferred.pipe() method is deprecated. The deferred.then() method, which replaces it, should be used instead.

Comes from:

whenValidate: function whenValidate() {
      var _Utils$all$done$fail$always,
          _this6 = this;

      var _ref7 = arguments.length <= 0 || arguments[0] === undefined ? {} : arguments[0];

      var group = _ref7.group;
      var force = _ref7.force;
      var event = _ref7.event;

      this.submitEvent = event;
      if (event) {
        this.submitEvent = _extends({}, event, { preventDefault: function preventDefault() {
            Utils.warnOnce("Using `this.submitEvent.preventDefault()` is deprecated; instead, call `this.validationResult = false`");
            _this6.validationResult = false;
          } });
      }
      this.validationResult = true;

      // fire validate event to eventually modify things before every validation
      this._trigger('validate');

      // Refresh form DOM options and form's fields that could have changed
      this._refreshFields();

      var promises = this._withoutReactualizingFormOptions(function () {
        return $.map(_this6.fields, function (field) {
          return field.whenValidate({ force: force, group: group });
        });
      });

      return (_Utils$all$done$fail$always = Utils.all(promises).done(function () {
        _this6._trigger('success');
      }).fail(function () {
        _this6.validationResult = false;
        _this6.focus();
        _this6._trigger('error');
      }).always(function () {
        _this6._trigger('validated');
      })).pipe.apply(_Utils$all$done$fail$always, _toConsumableArray(this._pipeAccordingToValidationResult()));
    },

and

// Validate field and trigger some events for mainly `UI`
    // @returns a promise that succeeds only when all validations do
    // or `undefined` if field is not in the given `group`.
    whenValidate: function whenValidate() {
      var _whenValid$always$done$fail$always,
          _this10 = this;

      var _ref9 = arguments.length <= 0 || arguments[0] === undefined ? {} : arguments[0];

      var force = _ref9.force;
      var group = _ref9.group;

      // do not validate a field if not the same as given validation group
      this.refresh();
      if (group && !this._isInGroup(group)) return;

      this.value = this.getValue();

      // Field Validate event. `this.value` could be altered for custom needs
      this._trigger('validate');

      return (_whenValid$always$done$fail$always = this.whenValid({ force: force, value: this.value, _refreshed: true }).always(function () {
        _this10._reflowUI();
      }).done(function () {
        _this10._trigger('success');
      }).fail(function () {
        _this10._trigger('error');
      }).always(function () {
        _this10._trigger('validated');
      })).pipe.apply(_whenValid$always$done$fail$always, _toConsumableArray(this._pipeAccordingToValidationResult()));
    },

P.S. If there is any other way to find out deprecated code, then do let me know. :)
