Add .eggs/ to gitignore
Add .eggs/ to gitignore

This directory keeps appearing, not sure why, probably when I rebuild
the tox environment. From the README file in this directory:

    This directory contains eggs that were downloaded by setuptools to build,
    test, and run plug-ins.
    This directory caches those eggs to prevent repeated downloads.
    However, it is safe to delete this directory.
