Binary Options Tester w/ Vdubus money management

Added implementation of vdubus's money management strategy to binary options tester. As before, the entry/exit strategy is just there for an example, modify go_down and go_up for your strategy as the short and long entry points. Also as before, do not use present variables (i.e. close, close[0], ema_6_min[0] in the example) in go_up and go_down, as this is akin to having future information. Calling past forms of compound present variables (ema(close,6)[1]) is fine.
