ability to trade automatically

[jhanstra]

Use an env variable AUTO_TRADE to allow coinbot to trade automatically on your behalf. Coinbot would analyze the trends of each coin market and make a buy/sell in an amount that reflects its confidence. e.g. if ETH price is dropping quickly, coinbot will wait for its best guess at a trough and purchase.

I'm going to set up a branch on my fork to work on a draft of this :)

I look forward to seeing some code!
