Just a quick compatibility update for The Flattening changes, with a few bonuses. Most new blocks and mobs are still missing.

NEW STUFF
* A ghost-like Phantom.
* Blue ice.
* Random variations for End Stone.
* New effect icons.
* Enderdragon Fireball (I didn't even know it existed!)
* Map markers: each one has a different shape to help decorate maps.

TWEAKS
* Updated texture names for The Flattening.
* Updated the recipe book GUI.
* A fast & dirty fix to water color. It's still over the top but there's not much I can do until Mojang keeps their hyper-saturated colors hardcoded.
* Sand is a little more wavy and grainy (for the unmptenth time).
* Dead Bush is a little darker.
* Fixed Shulker not having a custom texture.
