Multiple account support

[elena-v2]

I have a private account and I'd like to be able to pull tweets from it and have it used for the classification for the dominant emotion on the public account, for bonus accuracy of my true mood at that particular point in time. I don't particularly care about setting the name on the alternate account.

It'd also be useful for jail accounts, or if you wanted to become a two-headed emotional ogre with an unsuspecting friend.
