OK complete 2.7_03. Main changes are to the way TradeOrders are saved, there are now separate saves for Trade & TradeOrder i.e. Hibernate no longer handles this.

I also installed CodePro and Eclipse Memory Analyzer for eclipse, so there are many clean-up changes to the code-base and a change to the main controller. It no longer holds onto a copy of shared data-sets across tradestrategies during back testing (note this was redundant anyway).
