I've been doing some fixes this weekend.

- No longer possible to use the waste water or trash glitch to get upgrades and then sell it again getting negative cash;
- Fraud prevention by not accounting invested machinery as a cost but rather as an investment;
- Cleaned up the product graphs;
- Financial director and human resources now also apply to warehouses;
- Streamlined the turn processing code;
- Fixed the glitch with the production where the output of an early sector in the loop could be immediately used in a sector further in the loop as input, this made no sense unless there was some kind of time travelling active.
