Bugfix and Quality-of-Life Update

ATTENTION - this is part 2 of the major walls update, this one is destructive. Old saves (by now 3 months or more old) may not work or not correctly restore any walls built.

This update also fixes a number of bugs, adds French translation and more. Here's the full changelog:

• Removed old wall section prefabs
  
• French translation (partial, dialog texts still missing)
  
• Wayposts now create paths to connect to the nearest existing path
  
• Improved the interaction between game speed and monsters during the night (less chance for you to miss monster attacks due to high game speed)
  
• Increased the hitbox size of small monsters (rats, kobolds, goblins) in order to reduce the "monster phasing through walls" issue.
  
• Fixed: Work summary now scrolls when there are too many projects for the view size
  
• Fixed: Walls should now again be enabled correctly in the tutorial mission
  
• Fixed: Text bug (smelter/smithy mixed) in the Krobory Story mission
  
• Fixed: Steward sent back to school to learn counting (damaged/destroyed numbers should now be correct)
  
• Fixed: Kroburg story no longer launches the intro dialog and quest when you load a save game
  
• Updated Unity engine and packages used
