Classfind links

cross post from ChrisCooper/QcumberD#98

They requested that we have links to classfind.com to help people find classes. Marking this as an enhancement because it would be a good additional feature.

The classfind URL structure seems to be relatively straightforward, we could probably try to request the room name from the website, and if we get a 200 OK status, we can add it to the model?

I feel like this job would probably be allocated to the scraper or API, rather than the frontend, as I would rather not have the front end confirm whether a remote resource exists.

This is the site that I saw once, thought was a great idea, then completely forgot about and could never find again! It would be great to link out to this site from the frontend class view.

I agree that the scraper/api should handle the data though. Probably similar to the way that textbooks are currently handled.
