#label=(new_label) ⇒ Object
A Fedora object label can only contain a string value of up to 255 characters. If we try to set a longer value, it causes errors upon object save. Truncate labels to 255 characters. Note: this method maps to a method_missing hanlder that converts input into a String, so we use the super method first, and then post-process the output of that super method call.
