Addition of ImageStrategy to output images

This thing was missing in this module to output image(resized or whatever).

Usage(From controller):

        $image =  new ImageModel();
        $thumbnailer = $this->getServiceLocator()->get('WebinoImageThumb');
        $thumb = $thumbnailer->create('path/to/file');
        $thumb->resize(100, 100);// size in pixel
        $image->setPhpThumb($thumb);

        return $image;
Simple Usage:

        $image = new ImageModel();
        $image->setFileName('path/to/file');

        return $image;

For tests, please help me!

Hope this helps,
Waiting for your reply!
