Differentiate between which side an object is on

Browse source 
This means that if there's objects on both sides of the bot, then the tie is broken by which side has the most objects. Before, it would average out to the middle, so they wouldn't swerve at all, which is kind of stupid for rings, but can ruin the bot's performance for dodging items & players especially!
