Add Minecraft generators

[lucasqueiroz]

Is your feature request related to a problem? Please describe.
It could be nice to have Minecraft generators.

If you're adding new objects, please describe how you would use them
Maybe it could have the following generators:

.block() #=> Returns a block

.item() #=> Returns an item
.item(category = 'vehicle') #=> Returns an item in the Vehicles category (boat for example)

.entity() #=> Returns an entity
