Added a new give command to give players custom items.
usage: /cc give <player> <namespacekey> [amount]
There is a tab-completer implemented that will help you find your item more easily.
Fixed a bug where after crafting an item and clicking in the empty result slot of the workbench the item reappears and can be taken out, so you have double the amount!
Fixed a bug with shapeless recipes and removing the corresponding item amounts from the recipe causing errors.
