Remove old-style world goals #291
Description
Is your feature request related to a problem? Please describe.
As of v2.1.0 the old goal classes are deprecated, to be replaced by WorldGoalV2 and others. These new goals included the world state as a State argument, simplifying the implementation of new goals.
Describe the solution you would like
The old goal classes need to be removed, and the WorldGoalV2 need to become deprecated and renamed to WorldGoal. Similar for all other default goals as well. In a future release then WorldGoalV2 can then be removed again.
