Remove some appending behavior from GN.

Remove operator += and -= to append/remove a non-list to/from a list. Now you will have to wrap a single item in [] if you want to add or remove it. This makes the syntax more uniform since people were doing it randomly with and without [].

This removes the error of assigning to an unused variable. This ended up being too much of a bother, and causing errors in cases were you wouldn't expect it.
