reroute inherit color from parent node

Given that we cannot drag outputs from a node we need to create a reroute node to emulate that functionality.
To improve clarity in workflows we use colors for nodes.
I think reroute nodes created from the output of a node that has been colored, should inherit its color.

So if, for example, a rescale CFG node that is going to be used all over the workflow has been colour pink, if we drag it output and make it a reroute node it should inherit its pink color.
