Assign existing file txt node via right click on material attribute

Assign existing file txt node via right click on material attribute

- We create an object and assign a material.

- In the attribute editor we click on the createRenderNode port right of the color Attribute on the material

- we then select the file txt node and browse to a file on disk (This creates 1 file txt node)

- if we create another object and want to assign the same texture to a different material then many simply will click the same createRenderNode port right of that materials color Attribute and once again choose/select another file txt node (then browse and load in the same file). 

- The problem with this is this has doubled up the same node. We now have 2 file txt nodes in our texture library pointing to the same image on disk.

- it would be nice to right click on a materials attribute (such as color) and choose an entry such as: "Assign existing file texture node".

It is understood we could always open the hypershade and drag that first file txt node onto the new materials color attribute to make that connection (thus not doubling up the txt library with the same texture) but this is only possible with the hypershade open. Or, IF, Show DAG Objects Only is off in the outliner then we could drag and drop from outliner to the color attribute but this is only if that option is checked off.
