[Bug] Bone weights do not import when importing individual objects

[AdelQue]

Unlike when you import an entire model, replacing a single object in a model results in the object importing with no bone weights/vertex groups. The only way to get around this is by exporting the entire model, editing the object you want to replace, and then reimporting by replacing the entire model. The major downside here is that you lose the original normals of the unedited objects (the *.dae files don't export with normals).

What we're looking to see is that we can import/replace an object and maintain the bone weights/vertex groups of the edited model, without disturbing the rest of the model's objects.
