Removed GameState methods from block APIs
Created a BlockUtility class to get the block the player is looking at
Changed the return type of PlaceBlock, returning the ID of the newly placed block or null

Fixed compile issues and added new blocks

Thanks for doing the work to get it working with the latest update!

In the next week or two I'll try to find some time to do some work on the API to get the last outstanding API bugs fixed (and maybe add some new features)
