Removing debian/ directory so git branch is a clean upstream

I moved the .rst manpages up a level (out of debian/) and remove the rest of the debian/ directory.  This way, upstream is distro agnostic and clean.  Packaging will be managed by PAPT:

http://python-apps.alioth.debian.org/policy.html

We'll need one more upstream release (0.9.1) with the moved manpages to PyPI in order to upload a new version to Debian.  Once this is merged and PyPI released, I'll handle the Debian side of things.
