KNN PBI

OK, I've made some changes in the way the batch rankings (KNNPBI, ANPP, Vote) are calculated. Notably, the memcache is set using different sized batches and while I was messing about I made Vote account for ties (so it should be more stable). I'm not sure if this will fix the scores for DeepThought since I'm not really sure why they aren't being saved, I'll check back in a few hours to see if it worked. I know DeepThought is definitely getting the scores calculated because the ANPP and Vote show up in the main rumble score, so clearly it isn't being saved somehow.
