[Bf-codereview] Simplification of node muting and new detach operator (issue 5695063)

[brechtvanlommel at gmail.com]

I'd just use a different shortcut like Alt+D here, I don't really see
much reason this shortcut should include G key and then break user
automatisms. Tools like Duplicate or Rip in the 3d view also don't.

Further looks good to me.
