Tweaked alot of code :P
Player now has ship and uuid variables.
Player ship  variable is set with "player:setShip(ship)"
Player uuid is used as the key when adding a player to a ship's crew.
Ship-Editor now has a save button in the menu.
Ship now has a camera variable.
Added function for removing crew from a ship "ship:removeCrew(key)"
Compacted the code that handles placeing and removing tiles on a ship.
