Added new options: resizeToWidth & resizeToHeight.

Hello.

Nice tool. Thank you. I need an ability to re-size the cropped image, but I don't want to re-size the thumb box. i think adding 'resizeToWidth' and 'resizeToHeight' options is a good solution for this.

Also I noticed another similar feature request:

This code snippet make an image 100x100 px

        var options =
        {
            imageBox: '.imageBox',
            thumbBox: '.thumbBox',
            spinner: '.spinner',
            imgSrc: 'avatar.png',
            resizeToWidth: 100,
            resizeToHeight: 100
        }
        var cropper = new cropbox(options);
