There are several types of ponds added - I'm not sure all of them are actually used.
The code will need going through and fixing. At the point of porting the biome population method (where ponds are actually generated) I'll take a look and see what crap needs to be removed due to redundancy. Mud blocks, Quick Sand and Double Height Bull-rushes will be needed here.

mostly done and added to the gen.
need other blocks to finalise :)

Done
