Implement fortune for ores, glowstone and sea lanterns (#4897) 

* Implemented fortune for ores, glowstone and sea lanterns (but nothing organic or flint).

* Cleanup printf

* Stopped playing golf, gave the Camels a FirstHump and moved the FortuneDropMult comment. Thanks for the review :).

* Got rid of FortuneDropMult and replaced with Peter's massive optimization/simplification.

* Fixed default lapis max droprate (8 -> 9).

* Clamp max drops for non-redstone ores to 10.

* Comment justifying the clamp.
