Fix incorrect pylint import errors of nose.tools.
pylint cannot detect the PEP-8'd assertion functions that nose provides
in nose.tools, which leads to errors about missing imports. This
pylint plugin fixes that.
Installation Instructions:
1) Put this file somewhere on your PYTHONPATH.
2) Load it using either the --load-plugins command-line option, or
adding it to the load-plugins setting in your pylintrc.
