Slow when select() on datepicker with markers.

[Jaspur]

The calendar is very slow when there are markers added ánd you wanna select some dates. Pretty basis, but only tweaked the template. The select() is unchanged and this is causing slowness.

<mighty-datepicker markers="markers" ng-model="selected_dates" options="calendar_options">
</mighty-datepicker>

This options:

$scope.calendar_options = {
        callback: _callback_prices,
        months: 3,
        mode: 'multiple',
        start: moment().startOf('year'),
        end: moment().endOf('year'),
        before: moment().endOf('year'),
        filter: _filter,
        markerTemplate: null,
        template: "Tweaked template",
    };

With this Markers added:

angular.forEach(foobar, function(value, key) {
    $scope.markers.push({
        day: moment(value.date),
        marker: value.text,
    });
});
