Trading engine update

Sucess! As of this evening I have a live version of the new strategy engine running a breakout strategy in demo. Porting the old strategies over and refining the engine will likely continue for several weeks. I'm quite happy with how things turned out, but there is always more to do. I'm sure this will not be the last update to the strategy engine.
For the technical minded, let's just say hashes are really neat data structures, and without them this consolidation would not have been possible. ;-)
