Adding Boston!

I resolved the issue I described over e-mail by simply deleting Harbor Islands from the GeoJSON file (since it's somewhat of an odd "neighborhood" anyway). The git history preserves the old version, and therefore the bug.

With Harbor Islands in data (bug: cannot click the islands): https://github.com/daguar/click_that_hood/commit/c18bde1d1c4769ec7d82c31cb115a15cd2433863

Without Harbor Islands (final as committed): https://github.com/daguar/click_that_hood/commit/b2473f19f03185f3017c3d4261c77f420d21a280

The data comes from the file linked to in this thread:
http://www.zillow.com/advice-thread/Updating-Boston-Neighborhoods-Boundaries-Data/421449/

In describing the source, the author says:
"For all developers interested, here is a zipped shapefile showing the Boston zoning neighborhoods provided today by the Boston Redevelopment Authority office of Digital Cartography and GIS. These are a combination of zoning neighborhoods and zip code boundaries.
