Use glm::dvec3 for Camera LookAt/init

Browse Source 
Update Init(...) parameters to glm::dvec3, change LookAt to glm::dvec3 and adjust Camera.cpp to remove redundant glm::dvec3 casts (lookAt call and vector subtraction). These changes improve precision for camera lookAt vector in world coordinates above 4 digits
