- factored out 'business' code from the UI code
- moved to the new DEBUG_DECORATOR interface
- UI-less log file and log player classes as a step towards P&S unit tests
Adds Tom's internal P&S debugging tool. This is a work in progress and the code is quite messy for the moment, but I can't keep it in private branches forever and waste time rebasing it.
Note: experimental and *very unclean* code. Use at your own risk.
