Copying and pasting waypoints and allowing for bypassing default copy/paste behaviour.

It would be great if waypoints would be copied and pasted as well, when copying and pasting a selection of nodes. However, I can think of situations this behaviour is not wanted, so I want to propose the following.

a) Make it a user preference to set a default behaviour, that is, copying with or without waypoints when doing Ctrl + C.
b) Then, when pressing Ctrl + Shift + C, the default behaviour is bypassed, and the non-default behaviour is applied.

So, for example, if someone's default is to copy without waypoints, they can use the combination of Ctrl + Shift + C to do a copy with waypoints.
