Title: OnTradeSuccess and timeout fix

**Removal of OnTradeClose from the example UserHandlers**
This assures, that OnTradeSuccess will actually fire.

**Adding flag for CheckTradeTimout**
After other user accepted the trade, the CheckTradeTimeout kept on going.
However, at this time we are no longer expecting any action from the user.
This was causing trouble with large trades (especially when Steam servers are slow).
