re3-wiiu/src/core/Cam.cpp
erorcun 33e1f28239 Vehicle cam fixes 
- @ZLau92 's idea to remove 3rd person check on num 2/8.
  It was meaningless on III, probably not on VC tho.
- @Nick007J pointed out that camera wasn't checking objects,
  which was something done by someone to prevent camera to
  collide with traffic lights. Instead I enabled object check again,
  and comparing the result if it's a traffic light after the test.
