Dispenser survival!

This snapshot map, a lot like skyblock, sees you adrift on a floating island of dirt, only this time, you have a trusty magic dispenser, which shoots random items at you

UPDATEZ;

- Increased the chance that all minerals, especially iron, will spawn
- Added a 2/9 chance that it will spawn dirt or sand instead of cobble
- Updated the spawn chances incrementing with diamonds;  chances of NOT spawning cobble WERE
           1/9 1/8 1/7 1/6 1/5 1/4 1/3 1/2 3/5
   Now they are
           1/9 2/9 4/9 5/8 4/6 5/7 6/8 7/8 9/9

Known bugs;

- Items turn invisible when dispensed
- Hopper must be placed with a one block gap between it and the dispenser in order to pick up items

This took about a week to complete

Enjoy!
