Add Long Beach to Hoodguesser

NOTE: THIS DOESN'T WORK.

Decided to open a PR instead of issue since the hope is that this will get merged once it works.

Any ideas why it shows at almost-but-not-quite the right spot? It's almost right, but one level of zoom and a little bit of space off. I got the coordinates by importing from Zillow's neighborhood file, running through CartoDB (querying for neighborhoods that are just Long Beach, and the fields from the doc), then exporting as GeoJSON. If I run it through geojson.io, it shows fine, which leads me to believe that the issue's in syncing with the Mapbox code.

A quick look at the boundaries calculated also looks like they're appropriate...
