Fix crash on blueprint book creation, also refactor get_blueprint #41

Open sparr opened 4 years ago

sparr commented 4 years ago

LuaItemStack.active_index is 1 (not nil or 0) for a brand new empty blueprint book, which led to a crash when that index in the inventory was accessed.

While I was in there I also refactored get_blueprint from recursive to iterative.

Fixes #39
