curses.setupterm must only be called once per process

The class _AnsiColorizer in twisted.trial.reporter calls it for each supported() call. But this function seems to leak memory, so it should only be called if necessary. Unfortunately, there is no way to check if it has been called expect by trying to call a curses function needing it.
