start of turn explanations

[markus]

The reasons for the effects that happen at the start of the turn used to be logged in brackets e.g. (Wharf).
That's a bit bugged at the moment. Drawing cards tends to be logged, but not for (e.g.?) Dungeon. Other effects (Fair, Barracks, Coin from Caravan Guard, +buy from Wharf...) are logged without giving the reason.
