Expand MANIFEST.in to include basically everything.

Resolves #371.

Basically, @dstufft is of the view that the sdist should contain baaaaasically everything that is in the repo, except for things that literally cannot be used (e.g. no need for a .gitignore because this isn't a git repo, or a travis.yml). This patch does that.

You might be interested in adding a tox thing like:

[testenv:packaging]
deps =
    check-manifest
    readme_renderer
commands =
    check-manifest
    python setup.py check --metadata --restructuredtext --strict

That will check your README and make sure that all files that are commited to your VCS are either included or explicitly excluded from your sdist. In particular it makes it way harder to ship tarballs that are missing a file.

Sounds good to me. 👍

[Lukasa]

Aaaaand done.

[dstufft]

Cool, I can't double approve but

Thanks @dstufft and @alexwlchan!

Thank you :)

It'll make my pkg maintenance easier... and allow for those people that like to run the tests themselves.
