Perfecting cameras

Chase camera - set good distance, and view point set bounds so cant get
obstructed by mars, (had to created a bounded spheriod camera).
Created a more pinkish hue of Mars (added a Mars color)
Added a reset for the fly by cam
Added variables in globals to hold rocket scale and distance from the
rocket to mars.
Fixed error with glutWrapPointer being called in other modes besides fly
by
Removed cases to draw just a sphere and rocket by modifying model ( that
should not be modified after initizalizing)
