We do want clay and sand created when underwater, even in non-wet
environments and even desserts - where there is water, sand
and clay will always be created underwater.
- sounds played when a block is dropped.
- walker algorithm changed, will drop blocks closer before
going diagonal, but still prefer lowest deposit location.
- command overhauled: list, enable and disable worlds.
- falling blocks will now "crush" most plants, but not logs.
- decay to sand even in non-desertlike biomes as long as it
is underwater, same for clay in non-oceanlike biomes.
- config file now stores all params.
- shorthand '/sed' also gives access to all commands.
