Merge Nodes

[ImLucasBrown]

Is your feature request related to a problem? Please describe. Often when working you have two nodes you'd like to merge into one.

Describe the solution you'd like Select two nodes and trigger an action to merge. If attr names match the first node in the selection list wins. Also: When parenting a node into a child stack if the node's name matches an existing node merge it with that node rather than renaming it.
