Statistics Improvements (Zone Production, Quantity Filters, etc)

Would like to be able to use zones (like the new trucking zones) for production stats so that we can see what one particular portion of the factory is producing. Plus be able to filter the Quantity graph not unlike the Production Graph (ie, In Storage, On Trucks/Trains, On Belts/Pipes/Train Stations). This will allow us to better visualize what is in buffers (Storage) or being transported one way or another. To be able to quickly tell what is available to use in Quick Build (Unity Build) and what is not available.
