New features and settings

1. Add the /fillbiome command to bedrock 2. Add “puddles” which is a thin layer of water that forms during rainstorms and will dry up over time. These won’t affect player movement like regular water and are mostly for atmosphere. They can be manually placed when crouching and interacting with a block using a water bottle. 3. Add a on/off setting option allowing the player to enable and disable melting snow/evaporating puddles. Ie - light sources won’t melt snow layers and ice; puddles won’t evaporate over time. Maybe also add an option to disable puddles from forming naturally during rainstorms as well.
