[ghost]

• Converted to 2022.1 b2
• enabled GPU instancing for materials
• switched to deferred rendering for camera -Implemented fixes mentioned in Issue #9 by commenter "osilkin98" -Setup start scene
• Changed cast to plant for consume function. Moved all plant code to LivingEntity, which allows anything living to be potentially consumed. Also changed the consume speed from a constant to simply public and then changed the rabbits consume speed to 100 so it appears foxes consume them immediately. -Made plant consume speed alot slower.
