Combining websocket into betaclient

Now your orders are sorted in price order. The big change coming (in
beta stages) is streaming websocket will update the orderbook with
streaming updates from the websocket (Socket.IO) of depth/trades/ticker.
Also put a buy/sell 100 BTC protection limit into the API code because a
few times now I have omitted the price and it tried to buy 102.5
bitcoins at market value... luckily i didnt have that much but it spent
my whole balance, so now there is a protection in case you DO want to
spend that many. Goxtool was deleted. its not necessary.
