Add LOD to each AI model

Browse source 
Add a LOD (range animation) to each AI model if the property
/sim/rendering/static-lod/ai is set to any number greater than
zero. AI models get loaded but only displayed when closer than
the number given in the property (in meters).
If the property is absent or it's value is less or equal 0.0
than no LOD is added to the AI model.
