Tim/parature faq feed

I'm not sure about your first note because it seems like the importer will still need to do different things based on whether it's using the feed or a local file.  I was thinking that instead of having a local file, we could only pull a small number of faqs from the feed if the spec is being run.

For your last point, I had originally hoped to do this based on if the Article URL doesn't exist, the importing stops, but unfortunately it's not a continuous set from 1 to 379... I think a few id's don't exist, which is why I added that rescue statement.  So the way it is now might not the best solution but it keeps things simple.
