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.
