4.2.1-alpha

Additions:

• New config option: convertvanillaheads (default: false) - When false, avoid converting the type of head of when its block is broken. When true (or pre-4.2), the head is automatically converted to vanilla or skinned depending on the state of dropvanillaheads setting.
  • Setting this to false keeps heads as they were when placed and broken
  • Setting this to true forces items to convert to the desired drop type (vanilla or skinned) when broken.

Note: Legacy username-based playerheads are still updated to new texture-based playerheads for mobs (when broken) regardless of this setting, and they should be considered deprecated since 4.0.
(there were no vanilla/skinned overlap for legacy head definitions)
