Calendar does not allow to set default configuration about monthsNames and weekdays

[lquintana]

/**
 * possible and momentary solution
 * @weekdays = []
 * @monthNames = [] 
 */
ch.Calendar.prototype._defaults = {
        'monthsNames': monthsNames,
        'weekdays': weekdays,
        'format': 'DD/MM/YYYY'
};

The problem isn't in the code that is pasted on the comment. The problem is in the following lines
https://github.com/mercadolibre/chico/blob/master/src/shared/js/Calendar.js#L446
https://github.com/mercadolibre/chico/blob/master/src/shared/js/Calendar.js#L459
It have to get the ._options instead ._defaults
