blog updates—new pages & other confusion mitigation

…#PFR, short for Precarious Faculty Rising, is taking shape as a network. Yesterday, I changed the look and name (again) ►. Today, I added About, PFR Network, Canada and Global pages, and consolidated NFM to a single tab by adding, not just the main website link, but also the whole kit and kaboodle—Facebook, Twitter, Foundation, LinkedIn, G+ Community—to the newsletter archives on this site.
