Python 2 support, wait on action functionality, more actions

The bot should now work with Python 2. There were some issues with the print functions.

There is now functionality to make the bot pause for a random interval in between every follow/fav/etc. that it performs. Enabling this feature will make it less likely that your bot will anger the Twitter API gods.

auto_unfollow_all_followers() has been added, which unfollows everyone you're currently following.

Object-oriented version

Object-oriented version that supports multiple Twitter accounts via configuration files.

Flat script version

This version of the bot runs as a flat script and requires users to edit the script to provide API authentication information etc.
