image_url not working

[johnzw89]

Hello! Love this gem. I ran through the example in the readme however the parsed recipe object does not have image_url method.

eg.
require 'open-uri'
require 'hangry'
recipe_url = "http://paleoleap.com/lobster-salad-taro-chips/"
recipe_html_string = open(recipe_url).read
recipe = Hangry.parse(recipe_html_string)
image_url = recipe.image_url

I'm on version 0.0.2
When I use the same recipe_url in the demo, the image_url is found. Is it on a different version?

Thanks.
John

I think its due to rails 4 compatibility. version 0.0.13 depends on activesupport (~> 3.0)
I'm on activesupport (4.2.1)
