(ALL FIXED)

Known Issues: 

1. Score Formatting looks incorrect, and does not correlate visually to the appropriate user ID. However it still functions correctly, as the 1st person still possesses the 1st score and the 2nd person the 2nd score etc.
2. Score, being the sum of all damage, has a tendency to go negative when weapons capable of shooting through multiple zombies, due to the damage decrement.
