Lastest price bug

[edmondja]

There is a bug with ws.order_books. It seems that the asks and bids are correctly refreshed but lastest prices contained in the key "f" are not.

When you restart the stream doing
`ws = OrderBook()

ws.enable_log()

ws.subscribe_to_orderbook(pairs_list)`

Then, the dictionary ws.order_books contains the lastest prices, but still they are not refreshed automatically.

PS: it might be related to that issue #29.

I have similar bug like this.
Program runs for a long time , maybe 2 days or 3days , lastest prices and amount are wrong.
