Now uses correct endpoint names
Field name changes
Now delays by an extra second to help ensure we do not exceed rate limits.
Added an additional 5 accounts
Added an isAvailable(String endpoint) method which tells if a call to that endpoint is immediately available.
Now only uses the followers/list.json when the user has <= 20 followers and followers/list.json is available (otherwise it falls back to followers/ids in hopes that that is immediately available).
