Add player disconnect events to the output

[dragunoff]

Outcome time and state is already extracted but time of disconnect could also be useful.

Not sure we can do this reliably as the replay comes from the client so we're not guaranteed a disconnect event for all clients

[dragunoff]

Yeah, it's always from the point of view of the client - so I think it's expected to not have a disconnect event from everyone.

[AMHOL]

OK, will look into adding this
