Custom head textures no longer work

The custom heads (potentially unintended) feature is no longer working. Player skulls are still functional, but custom textures obtained using this* don't show textures.

Unintended or otherwise, this was an exceedingly useful feature to map makers and redstoners and it would be an immense shame to see it go.

In otherwords, please fix or the hugs are only hollow. :'(
