Exchange: connection, URL and livedata

[Benjamin Cordes]

To test connectivity there are several steps needed:

Global.exchange = new Exchange(ExchangeFacade.BTCE);
TradeInterface ti = ExchangeFacade.getInterfaceByName(ExchangeFacade.BTCE);
Global.exchange.getLiveData().setUrlConnectionCheck(ti.getUrlConnectionCheck());

Better would be if exchange can handle its own connectivity, and the connection variable.
