Temporary Hack: provide B-Bone scale versioning for files with old patch.

Run the versioning code for the conversion of bbone scale to an xyz
vector if it has fields that correspond to the old version of the
patch before that change requiring versioning.

The actual Y (length) scale value from the old patch isn't versioned
and will be lost, requiring manual fixing.
