a) debug Camera Matrices. enable with _IRR_COMPILE_WITH_90_DEGREE_CAMERA.

- allow ICameraSceneNode to accept any values and correct in buildCameraLookAtMatrixLH with normalize_camera_direction.
 if disabled defaults to the current v1.9 normalize
b) add initial Rotation to MayaCamera Constructor default 0,0
c) switchToMayaCamera in Examples. Clones FPSCamera default disabled
