Temporarily disabling the ipdoctest nose plugin.

This plugin was causing problems with Twisted.  We need to go through
the plugin to find the source of the problem.  For now, our test suite
passes though.

 """IPython Test Suite Runner.
 
 This module provides a main entry point to a user script to test IPython itself
 from the command line.  The main() routine can be used in a similar manner to
 the ``nosetests`` script, and it takes similar arguments, but if no arguments
 are given it defaults to testing all of IPython.  This should be preferred to
 using plain ``nosetests`` because a number of nose plugins necessary to test
 IPython correctly are automatically configured by this code.
