Use id_str instead of id for Twitter IDs

[adamwathan]

Noticed the id field was being used for a user's Twitter ID. Twitter highly recommends using the id_str field instead due to issues with how large integers are handled in a lot of systems. It's probably not actually an issue in practice in this case, but I've personally run into issues due to this when working with the Twitter API in a Javascript environment, and since it's recommended by their documentation, it seems like it's probably a better choice than using the integer field.
