Shields don't load their colorings and colored shields are not craftable

My Shield item had much colors on Spigot, on Glowstone it loads as a blank one.

If i try to craft it with a simple banner, i get this message in the console:

```
2016/08/23 21:50:04 [INFO] FastFelix771: [rejected] WindowClickMessage(id=1, slot=0, button=0, transaction=9, mode=0, item=ItemStack{SHIELD x 1})
```

The items i used to craft are also bugged away.

The issue names no source files, tests, or entry points. Reproduce shield coloring and banner crafting on Glowstone versus Spigot, then trace the shield and banner item handling; done means colors load correctly, colored shields can be crafted, and crafting items are not lost.
