Node Editor - More Cleanups (Reshuffling):

- removing duplicate chunks of code -> hide unused sockets now works
- moving some functions to the files that they get called from -> view all/home
- made duplicate a macro operator like the other places that work like this, eliminating the unnecessary transform-related property there still
- removed a few chunks of unused code
