[Bf-committers] Node link swapping

[Lukas Tönne]

I've made an initial implementation for this:
https://developer.blender.org/D483
Should be ready soon, just needs a few tweaks for backwards compatibility
and a list of nodes that can use the feature in a meaningful way.

Hope you don't mind that i added all participants here on CC, feel free to
unsubscribe. It's easier to continue discussion on the tracker imho.
