Looks like we need the '.py' filename extension to call `rst2man` in
regular installs.

Apparently `pypip.io` is not longer active. It looks like `shields.io`
offers even much more badges.

Tell about the new default wordlist.

We must tell, that this option does turn words into lower-case
automatically.

Fixes #32.

We support py3.5 but not py3.2. This was yet told incorrectly in
README.

Thanks to @lieryan for bringing the problem up.

The output changed, due to listing the new EFF list.

Kudos to Joseph Bonneau and EFF, also copyright-wise.

The help page displayed in README should reflect the real help page.

also updated README

Fixes #16

Thank you!

"Diceware 8192 list" is not a valid reference any more.

This wordlist was renamed to `en`. It is the default wordlist.

Remove heading of configuration file section of README. It was more confusing than helpful, I think.

If we talk about configuration _files_, then tell it.

Give hints, how to customize configuration.

Tell about dash by name.

The README is evaluated by standard docutils when released on
pypi.python.org. These do not understand most text roles (like
``:class:``) recognized by `Sphinx`. As a result the README will be
displayed as raw text on PyPI which looks ugly.
