Update 0.1.47.3

When my dinosaur hatchlings were being killed more often than usual by much larger dinosaurs I thought it was time to add in the following: the larger the size difference between two dinosaurs is the less likely they are to attack eachother. Hungrier carnivores look harder for prey so a dinosaur being smaller or larger won't matter as much in this scenario.

• Fixed a case of dinosaurs not being able to reach their food.
  
• Fixed a case of dinosaurs getting stuck on eachother.
  
• Fixed some cases of dinosaurs looking like they were running when they weren't really running.
  
• Dinosaurs get thirsty and hungry twice as slowly.
  
• Dinosaur thirst and hunger has been doubled.
  
• Calling for help no longer makes the player thirsty.
