New Social feed

[Edit 12Jan2018]

It turns out that we won't get data from AA or MidMichigan - something to do with the way that they publish their pages.

I have added a new category to the Social Feeds called Local societies.  I has already added articles from the West Michigan groups Facebook page.  It should pull articles from the Ann Arbor group soon.  As I can identify other groups with Facebook pages, I will add them.
