README.md missing in v0.6

[chid]

The current version in pypi has an issue with a missing file (README.md), it does not appear to be within the package.

  Using cached django-silk-0.6.0.tar.gz
    Complete output from command python setup.py egg_info:
    warning: pypandoc module not found, could not convert Markdown to RST
    Traceback (most recent call last):

        README = read_md('README.md')

    FileNotFoundError: [Errno 2] No such file or directory: 'README.md'

I made this change so I could convert markdown files to rst when pushing a release to pypi. This reduces the need to manage two readme files. My mistep was assuming the setup was including the markdown version. I will update the package includes to include that file.
