Ability to duplicate nodes / blocks

[must]

It would be really nice to have the ability to duplicate nodes and blocks (With the shortcut of copy paste and also from a right click menu as an option).

Blocks reference calls / component logic that is used in a node.
Nodes are the macro-logic end-points.

This is interesting because it simplifies creating the visual logic in some cases where reusing a graph is relevant either in package development or in actual development on top of the platform.
