Convert README to reStructuredText (.rst)

What do you think about converting README to RST format?
Github understands both Markdown and RST, but the PyPI website only renders RST, and at the moment the package page doesn't look really nice: https://pypi.python.org/pypi/django-tenant-schemas/1.4.7

At the same time Markdown and RST are really similar in terms of markup, and look pretty much the same in rendered form.

(I used [pandoc](http://johnmacfarlane.net/pandoc/) for converting.)
