in reply to Null vote is incorrectly labelled?

I think +=0 is accurate, since the idea is that you're performing a mathematic operation on the node's reputation, which is an integer. If you make the null vote say "null", it doesn't follow the pattern set by the ++ and -- options. Instead, I propose that we change the name of the null vote option to the "increment by zero" option, which is much more descriptive and only 6 times the number of syllables.
