Add expose "didPickPhoto" as delegate from DZNPhotoPickerController about dznphotopickercontroller

[dzenbot]

DZNPhotoPickerController intends to mimic UIImagePickerController as close as possible, while still adding some cool features. It has not being designed for multiple photo selection, like Whatsapp's or Facebook pickers. That goes a little bit out of the project's scope.

Maybe an option would be, with the help of a bool flag, to limit the resulting payload only with the source url of the selected photo, no UIImage, so the UI doesn't block because of downloading. Then, it's your app's responsibility to download the images whenever requiered.

Feel free to collaborate on this one.

Yes. Agree. no UIImage only bool flag.

To make this work, you'll need to set 2 flags:
picker.allowsEditing = NO;
picker.enablePhotoDownload = YES;

You will then get all the photo metadata, expect the UIImages, after the user selects a photo thumb.
i.e.

{
    "author_name" = "Mary G";
    "author_profile_url" = "http://500px.com/Mary1118";
    "author_username" = Mary1118;
    "source_detail_url" = "http://500px.com/photo/60913694";
    "source_id" = 60913694;
    "source_name" = 500px;
    "source_url" = "http://ppcdn.500px.org/60913694/9a3ac952139b2564ec90e67d3423ce4f0be389ad/4.jpg";
}
