Fixes the init.author.* settings when doing npm init

The init.author.* settings in .npmrc were broken (ignored when running `npm init`). 

This fixes the issue by pulling in the config options explicitly since I couldn't find a `config-chain` method to do that - npm.config.get() without params returns undefined which is why this broke.

Bump up init-package-json as well, since it was out of date, 0.0.7 was released 6 months ago, cf: https://github.com/isaacs/init-package-json
