Facebook auth scope 'read_stream' deprecated

If I remove the read_stream scope from app/controllers/sessions_controller.rb#53 it throws the following exception on callback:

@TechWilk I just pushed 1b73d1b which might fix this. I don't have a FB app setup, so I can't test at the moment, but I can get it set up a bit later and try it out. Or maybe you can give it a whirl. Thanks!

I'm going to close this as I think it's fixed.
