Holy shit, lots of activity at Team Liquid.
Winner detection is tough - it's not stored in the replay so you kinda have to guess.
I'm working on adding in the list of actions the PHP version did. As far as actually parsing the replays, I'm at about parity with the PHP version, which is good. Now it's just a matter of mapping action IDs to the actual action types.
I'm also planning on making a replay database that stores all that parsed info, but right now it's not built-in.
