Alpha 5 patch 9 hotfix 43

Had to do some really boring work on code refactoring, especially for livestock management which has been a fertile ground for various kinds of bugs for quite a long time. But as I said earlier the main priority is to release a final version of the game, so polishing the fundamentals is just as important as adding new major features. Meanwhile some new features did slip in as a side effect of said refactoring.

Added/changed:

• New fences will now replace previous ones if built over (no overlap)
• Default animal feed stock values are now proportional to livestock size and consumption
• Trade boats will now fold their sails while moored
  
• Trade boats will now lower their mast to pass under a bridge
  
• Stable can now have dedicated pasture
  
• Horses can now also graze on a field
• Horses now require both grain and hay (or grass) for optimal health
• Stables/saltworks/wagon sheds in old saves will get certain amount of grain and hay for free if needed for transition to new mechanics
• Stable now has "Livestock limit" slider
• Can now change a field to fallow even if not all harvest stooks gathered yet
• Animals with lower health produce less resources when slaughtered
• Oxen in ploughs can now be combined if two ploughs with only one ox
• Now visualizing connection to linked building on warehouses and cart parkings
• Animals now have health property which depends on feed quality
  
• Livestock buildings now have feed rationing setting for emergencies
  
• Draft animals with lower health move slower
• Milk and wool production also depends on animal health now
• Updated help pages for buildings with new features
• Added a notification if grass quality is low around a dryer
• Added an option to allow forestry workers to plant trees
• Added a notification on a wagon shed and farm if a draft animal replacement is needed
• Clicking on wagon/boat/plough icon will now focus on it
• Added a health bar for plough and wagon animals
• If ploughing skipped on a field, but a plough arrived to farm, the field will now switch back to plouging if possible
• Clicking on ordered cart/plough/etc. will focus on a building where it's being built
• Now the "Next" button in fields works even if ploughing started
• Now showing notification if there's no available cart to supply resources
  
• A few slight optimizations

Fixed:

• It was possible to remove fences from building by demolishing an adjacent building (only fixed for new builds)
• Windmill didn't function properly
• Animals didn't consume water when on pasture
• Livestock feed consumption could depend on game speed and fps
• Potentially fixed all the weird behaviors related to slaughtering and relocation of animals
• Slaughtering from saltworks produced twice the amount of resources
• Another case of wrongfully blocked buildings
• Some UI overflow conditions
• An incest loophole for widows and widowers
• Bad performance when forestry is selected (on some machines)
• Ploughing visuals were lagging behind the plough in some fields
• Cowshed or stable manager could take the last animal required for breeding
• Boatyard could show inaccessible orders in total count
• "Optimize bulls livestock" could misbehave sometimes
• Rowhouse lods didn't have color variation
