Transport Fever 2 - Demand Overhaul Mod

Demand Overhaul mod for Transport Fever 2. The update includes industry and cargo adjustments, bug fixes, and menu updates.

Update 1.5:
- Made some minor changes to some industries and its cargo
- Fixed the bug that didn't allow some of the industries to properly level up
- Added 8 submenus in the industry build menu to better organize the 70 buildings
- Added a script so that the game will choose the corresponding rules depending on the climate during map generation (thanks doug)
- Added a script so that custom vehicles should all be compatible (thanks doug)
- Updated the accompanying guide to reflect the changes made, this includes updating the several tables.
- Added icons for the build submenus and for recycling and electricty

Industries that are already placed will still not change their demand so everything is in its 2000 values regardless of the year, including the material recovery efficiency.
Still to get more than 6 cargo items per town sandbox mode is needed; or the limitation can be used to make more challenging games
