Fix pid issues in hots branch

[dsjoerg]

There is a new test in test_all.py in ggtracker/sc2reader to demonstrate the bug.

def test_pids():
    replay = sc2reader.load_replay("test_replays/2.0.3.24764/Antiga Shipyard (3).SC2Replay")
    assert replay.players[0].pid == 0
    assert replay.player[0].pid == 0
    assert replay.players[1].pid == 6
    assert replay.player[6].pid == 6

    eventpids = set()
    for event in replay.events:
        eventpids.add(event.pid)

    assert eventpids == set([0, 6, 16])

This is actually a symptom of the replay.initData format being completely different in new versions of HotS. It now includes player clan tags!! Possibly another 5-6 bytes of extra goodies I haven't figured out yet. I'll try to push a patch later tonight.

Done!
