* Adds support for liqui, localbitcoins, okcoin, poloniex, wex and yobit. Splits up open order methods for poloniex

* Adds bithumb, okex and zb support. BTCC for another PR

* Updates bitflyer, bithumb, bitmex, coinut, okex and zb cancelAllOrders method to cancel via enabled currency pairs rather than a singular currency

* Adds tests to all exchanges to test wrapper function CancelAllOrders

* Fixes OKEX and huobi, btcmarkets, kraken, okCoin cancel order implementations
