B-Bones: split the Scale In/Out properties into X and Y values.

As far as I can tell, there is no technical reason why the B-Bone
segment thickness scaling can't be separated into two axes. The
only downside is the increase in complexity of the B-Bone settings,
but this is inevitable due to the increase in flexibility.

Updating the file is somewhat complicated though, because F-Curves
and drivers have to be duplicated and updated to the new names.
