Updating jsts dependency for react-native compatibility

[vespakoen]

Hi,

The current version of jsts that this package uses exports a global (jsts) unexplicitly (i.e., not window.jsts)

This breaks the package in (react native's) strict mode.

I updated the dependency and used the GeoJSONWriter (the GeoJSONParser is gone in the latest version of jsts).

When shrinkwrapping I got weird results (probably because I am using npm@3?) It adds all dependencies (including devDependencies) to the shrinkwrap, and marks jsts as @latest, I guess the idea is that it locks it at a specific version, so I guess we will have to update the npm-shrinkwrap.json manually.

Thanks for turf, I enjoy using it a lot
