Auto Clean up Composition Nodes (all and/or selection)

A Vuo editor feature to Auto Clean up nodes, based on node connections. This feature would make it easy to arrange nodes automatically if the user chooses. Can be for all compositions on canvas- or a highlighted selection. (or possibly just for highlighted selection, and then simply select all).

This may make it easier to organise, and so much quicker to lay out nodes if we choose to use it.

Opened for voting.
