consolidating result options in an anonymous class

Wraps the params in the results function into a class so that Croppie would properly read the format and other params. Otherwise only the type param is taken into account by Croppie library.

Thank for your PR. It looks good to me, but I also think that we should abstract the WebSetting model as well, move all JS codes out of this model, it would help us get rid of using conditional import as the current approach. What do you think?

Thanks for PR, I am going to close this because of #350
