Scott 0fbf8b172a Websocket orderbook buffering (#333) ...

* Initial commit setting up a map orderbook system with a buffer. It will write to the buffer, sort apply to main orderbook and then process.

* Moves namespaces again

* Updates orderbook to use a sweet new WebsocketOrderbookUpdate type to handle all updates whether its using ID or not. So good. Adds many tests

* Starting to implement orderbook update handling per exchange. Updates namespaces again. Hopefuylly will find a way to update via ID not timestamp, too many endpoints dont provide update timestamps

* Changes orderbookbuffer to use BufferUpdate type instead of orderbook.Base to achieve more functionality and no need for type conversion functions. Updates tests

* Updates all instances of ws.orderbook.Update. Simplifies some orderbook logic

* Introduces toggleable buffer. Renames orderbooks. Completes implementation for everywhere but OKGroup due to hash calculation

* Adds poloniex orderook sorting support

* Enables bitstamp and hitbtc orderbook sorting. Fixes poloniex's sorting

* Renames namespaces and combines monitor and connection into wshandler. Removes unused SPOT const. Changes how orderbook stuff is loaded. It is done in startup with a setup. Removes exchange name from loadsnapshot as well
