Patch 1 for version 1.1.4

More extensive patch coming later when I'm done with the new Disinfection patch.
I got some cool ideas for some non-lethal events during the earlier days/first delivery, to add a little variety and spookiness.

For now here's some minor QoL tweaks:

• Added simple instructions board to Lorry,
  
• Lorry brakes are twice as strong on Delivery 1, slightly stronger than before on Delivery 2.
