Fix rounding error for GHS trading on CEX.io

We were rounding the GHS amout to sell up, which caused some trades
to fail because of insufficient funds.
Fix minor issues which can cause the trader to halt
Add support for trading

New trader actor that acts on trading advice and triggers the appropriate
actions using the portfolioManager.
Fix issue with callbacks in portfolioManager

There's cases where a callback can be missing to one of the
calls in the portfolioManager which caused an error (and halting the
trader). Added a check if we actually had a callback before triggering
it which keeps things running smoothly.
