Cylces node setup improvements

[benthillerkus]

After watching Andrew Price's recent tutorial on avoiding texture repetition, I think there are 3 things that we could improve:

1. We should add a texture coordinates node and connect every texture map with that
2. We should wrap all of the texture maps inside of a node group so that the texture can be used inside of other materials aswell
3. We could consider adding a random rotation setup aswell. Maybe with a checkbox that toggles if you want to add it to the node tree or not. It's super simple, but surprisingly effective.
