Cut/Copy/Paste

[hapes]

As a user, I want to

select multiple items
be able to issue the command to copy (leave the original) OR
be able to issue the command to cut (remove the original)

Then, issue the command to paste, resulting in a duplicate of the original selection. This does not include connections to items outside the selection.

UX: can we do ctlr-x/ctrl-c/ctrl-v? That's the optimal pattern. Also include buttons in top bar or in the main canvas when a multi-item selection is active.

See #3 which requires the same selection tool
