Title: Tweet Activity Summary Support (# favouriters, RTs & replies)

Hi Josh,

Added support for the unofficial tweet activity summary (# favouriters, RTs & replies) as used by popular twitter clients (official, tweetbot, ...) in an TweetActivity object. (API call: https://api.twitter.com/i/statuses/[tweet.id]/activity/summary.json).
