LeoCAD not fully loading model

[Philippe Hurbain]

It turned out that LeoCad cannot handle the 0 NOFILE meta or duplicated ones.
Just removing all 0 NOFILE meta's the model loads fine.

More specifically, LeoCAD stops loading the file if it encounters two successive 0 NOFILE metas.

However still: the file does not load in MPDCenter...

Works fine here, with zero or one and only one 0 NOFILE at the end of each submodel.
