Fixed retweet detection

Because a retweet is a tweet referenced from another tweet, the current implementation dynamically allocates memory for the retweeted status and has to manually copy the pointed to data around. It's not a very pretty implementation and may get tweaked at some point soon. I don't like having to implement the big five.
