[plt-scheme] Scheme Boston meeting location for Mike Sperber talk

I'm sorry to send yet another message about this, but the Scheme Boston
meeting will not be in Egan 366 at Northeastern, it will be in West
Village H (WVH) 366.

Directions to WVH:
    - 440 Huntington Ave at Parker Rd, right across from the Museum of Fine
      Arts.
    - On Northeastern's campus map (http://www.campusmap.neu.edu/), it's
      in the area marked "Under Construction" between buildings 22 and 36.
    - Just about halfway between the Northeastern and MFA stops on the
      green line, and an easy walk from Ruggles on the orange line.  Also
      convenient to bus #39.
    - There may be parking available on Parker Road next to the
      building, or not.
