[Rails] Feedzirra and custom fields

When we read RSS on any programming language normally only the default fields are necessary, but sometimes a comment page link, a subtitle or other important info is stored into custom fields.

You can even map to field to same single resulting field, when you have two different sources with different subtitle fields for instance.



That solves the issue
