Finish cleanup of setup.py and tests after dead code removal.

This completes the cleanup from Brian's previous commits, so that
trunk again installs/tests correctly.

 """IPython Test Suite Runner.
 
 This module provides a main entry point to a user script to test IPython
 itself from the command line. There are two ways of running this script:
 
 1. With the syntax `iptest all`.  This runs our entire test suite by
    calling this script (with different arguments) or trial recursively.  This
    causes modules and package to be tested in different processes, using nose
    or trial where appropriate.
 2. With the regular nose syntax, like `iptest -vvs IPython`.  In this form
    the script simply calls nose, but with special command line flags and
    plugins loaded.
 
 For now, this script requires that both nose and twisted are installed.  This
 will change in the future.
