Aaron Kimbrell d870207a9f fix: place brick by brick models by the bottom middle of their bricks' box ...

When a brick by brick save is split into models, each model was centred on
the middle of its bones' origins, on the lowest origin. A brick's origin is at
a corner of it, not its middle, so a single 2x2 came back offset by half a
brick, and the model's floor was taken from the origins rather than from the
bricks.

Now each model is placed as the live server placed it: at the bottom middle
of the box around its bricks. Each brick's own box comes from the client's
brickdb by its design ID and is turned and moved by its bone (all 8 corners),
and the model's box holds every brick's. Its x and z middle and its lowest y
are the new origin, still snapped to the 0.8 grid on x and z, and every bone
moves by that; rigids and rotations are untouched. A design the brickdb has no
box for counts its bones' origins, as before, so no brick is left out.

Lxfml::NormalizePosition and Split take the boxes by design ID, and the brick
by brick save passes the ones read from the client (read on the first save,
then kept).
