Added support for the Shipwrecked DLC.
The Pig Head crafting recipe will instead product a Wildbore Head when performed in Shipwrecked.
The Touchstone crafting recipe will use Limestone instead of Marble when performed in Shipwrecked.
The activation ritual will instead use Wildbore Heads when performed in Shipwrecked.
The activation ritual will no longer fail because a nearby head is not on wood, as long as at least four valid heads are present.
Added a configuration option allowing the activation ritual to consume the heads that are used.
