Title: Add swamp tree generation

This pull request will break plugins, because it makes changes to BlockChangeDelegate. Unfortunately, this is needs to be done because WorldGenSwampTrees uses setTypeIdAndData but BlockChangeDelegate only offers setRawTypeIdAndData. BlockSapling is also modified because it uses a BlockChangeDelegate and needs the new methods.
