Some more PGR corrections

They are still in process, though many have now been made and gone live.  One important one, worth flagging, concerns the omission of Arizona State University from the list of recommended terminal MA programs.  ASU had long been on that list, before they started a PhD program, and then they tended to rank in the top 50 PhD programs in the US.  We noted the demise of the PhD program earlier this year (so ASU was not included in this year's survey), but neglected to put ASU back into the list of recommended MA programs, where it certainly belongs given the caliber of the faculty.
