- Make ipdoctest a little cleaner by giving it separate option names. This is in an attempt at better isolating it from the rest of nose, because we are seeing intermittent Twisted errors when it is enabled. However, I still see them sometimes. - Also, make the reference counting tests a little less verbose.
