'Drunken Sailor' as a playable shanty.

This is the song that i think about when i think about this game. I understand that the main theme is technically a rendition of it, but it's vastly different. I also appreciate that the tune is used when you pick up the Chest of a Thousand Grogs (albeit out of tune), but i would love it if it was a fully implemented Shanty. From what I understand, Shanties are hard to develop and add to the game, but I would be more than happy to wait. There's also a couple spaces free in the more section of the shanties list, and i think this song would be a perfect fit for one of those slots.
