BF - allow nose with-doctest setting in environment IPDoctest replaces the normal doctest plugin. Previously we did this by initializing the builtin plugins but skipping the doctest plugin. However, if the user has a noserc file with 'with-doctest=1' or the environment variable 'NOSE_WITH_DOCTEST', then nose will try and initialize the doctest plugin when it isn't there, and barf. This commit defers the removal of the doctest plugin to the configuration stage, so doctest can be enabled before it is thrown away by us.
