Add new item DYNAMITE for blasting away land tiles leaving water!

[jswarts]

For those of us who love the terraforming aspect of the game... 

It would be amazing to have an item like Dynamite that could be crafted in order to blast away land leaving water. I love basing around areas with sporadic water where I can plant fig trees, etc. Giving us the ability to do this on our own would add to the level of control and mastery we have over the world and would be a lot of fun and open up some really cool creative avenues. 

Being able to craft Dock Kits was a game changer in this regard too. Having an item to do the inverse (i.e. deleting land) would compliment this. 

I know you can use 4 gunpowder to remove a dock tile. It seems like gunpowder would be way to weak for removing a land tile and that's why Dynamite seemed like a good idea, as it would be really powerful, and its crafting material should probably reflect that.

Additionally, I could see some really interesting uses for it in the caves.

Enables too much griefing as is. I think it is too much power for players to have anyway. At least dock kits are rather expensive, and can only be built in shallow waters.

I like this, but I feel like if they were to add this, they should add the ability to make properly tiles rather than just docs on water
