Infinite Dimensions

A major update adding:

• the /warp and /warp-id commands
• interface to add "easter egg" dimensions via configs
• several new density function types for usage in these dimensions
• support for having dimension IDs go to the long limit instead of the integer limit
• ability to add salt to book text -> numeric dimension id encoding

and also:

• making structures a bit more common
• removing the seedDependentDimensions gamerule in favor of salt.

Make sure to wipe your config/infinity folder before updating to this one.
