DarkflameServer now normalizes UGC model LXFML around the model's own
origin and stores the model's world position and rotation in
properties_contents, the same as for prebuilt models. The property
viewer only applied that transform to prebuilt models, so every
player-built model rendered piled up at the origin.
Pass each UGC model's stored position and rotation to the LDD converter
and apply it to every brick (including flex parts) when building the
scene.
