Minifig Head - Numbering of b and c variants

[Magnus Forsberg]

Hi Gerald,

This issue have been up at least twice before.
Here  and  Here

Some of the affected heads are still at the PT, and I think the conclusion was that we should not make both b and c-versions.

But the issue might have to be solved if/when there is a decision about DesignID and ItemID  in Physical colour shortcuts.
