Update 0.2.51.7

----------------------------------------------------------------------------------------------------
Mechanics:
----------------------------------------------------------------------------------------------------

• Dinosaurs now have oxygen which is used for staying underwater. While your dinosaur is swimming, the oxygen gauge becomes visible over where the thirst gauge was. Oxygen depletes while underwater. If a dinosaur stays underwater after their oxygen fully depletes they will start losing health every second until they either die or resurface for oxygen. Older dinosaurs have more oxygen capacity than younger dinosaurs.
  
• Terrestrial dinosaur AI now has a 25% chance to accept a wandering destination that would make them stop in water, down from 100%. Terrestrial dinosaurs were enjoying swimming a little too much. Aerial dinosaurs no longer accept wander destinations that would make them stop in water. Amphibious dinosaurs can wander in and out of water freely. Aquatic dinosaurs will only wander within the water.
  
• Food now floats and moves with the surface of the water.
  
• Dinosaur corpses now float and move with the surface of the water.

Bug Fixes:
----------------------------------------------------------------------------------------------------

• Fixed a glitch where amphibious dinosaurs would go back and forth between the surface of the water and the ground really fast if the water they were in was very shallow.
  
• Fixed a glitch where dinosaurs lost their target but were still in the chasing state. This was causing the dinosaur to walk without playing the walk animation.
  
• Fixed a glitch where dinosaurs that did not thirst (sarcosuchus and archelon) were not regenerating health passively.
  
• Fixed a glitch where dinosaurs that were idle were moving.
