Small Camera Change + Energy changes for Character States

Fact. The Rover is actually quite above the terrain(for those who don't
see it). Messing with it caused the Rover to fall through so I left it
alone. This is why I don't think a panning up/down camera will be a good idea, because the gap between the terrain floor and the Rover is quite obvious. Scripts changed are the Camera, EnergyBar, and
ThirdPersonController so if you are having issues with gameLevel.unity,
you don't need to bring my changes to the scene; just the scripts are
enough.

I'll look into a rotation for the Rover later on today. Also, holding
the F key while not moving will orient the camera back to behind the
Rover, kinda like a reset feature. The Rover will not climb up steep
slopes; there is a check in ThirdPersonController.js with the
ControllerColliderHit to not jump upon hitting a surface with a certain
normal or above. Feel free to change the values of decayRates in the
Controller.js
