Update 0.9.20

The new large map still needs some work, but even so, it's better than nothing.

• Significant changes to the UI: fewer large elements, all control hints are now in the same style.
  
• Transport now has control hints.
  
• Vehicle controls have been expanded with alternative keys. (more relevant for gamepads)
  
• Minor changes in French texts (thanks to the unknown editor)
  
• Multi-tool management: simplified tool switching (no need to go to the construction menu every time)
  
• The construction menu is now organized into tabs.
  
• Instead of the Log (F1), a map now opens. The log has been moved to an additional tab on the map. The default key has now been changed from F1 to M (for new players)
  
• Fixed an issue where the message log was displayed in the wrong chronological order.
  
• Fixed a bug where the equipment slot interface was working where it shouldn't.
  
• New… stuff at the Nuclear Desert level.
