Bug: TimeOnPoint and TimeOnPayload appear to always be 0?

Possibly related: #41

Was looking at a replay recently (dated 11/9) and saw that a player received the Point Guard award on Volskaya but had the TimeOnPoint stat recorded as 0. Similarly, saw a replay on Hanamura Temple (also from 11/9) that had completed objective phases, but all team members had TimeOnPayload recorded as 0.

Either these aren't the right stats to look at for these maps in SScoreResultEvent, or they're always 0. Would be good to have this data in there!
