Better Swamps

Swamps will have a few new features. #1 now Lilly pads will have a little green tail in the water and also have a variant that has a pink flower on-top. #2 cattails can spawn on the shore of swamps. #3 duckweed can be bonemealed and spawn on-top of swampy waters. Slime have a high chance so spawn on duckweed. #4 the old Swamps gets it's own wood type. The bark will be the same colour as now but the planks will be deep green
