LDView povray export

[Orion Pobursky]

 I did a quick test rendering the following scene:

Code:

// -------------------------------------------------------------
// Test code

#undef LDXSkipCamera

// -------------------------------------------------------------
// LDView models

#include "ldv_nice_dune_rover_new.pov"

POV-Ray issues a warning, but thankfully does not halt the render with an error.

Just throw an #ifdef in there.
