Merge branch 'release' of git://github.com/melinath/philo into release/0.9.1

* 'release' of git://github.com/melinath/philo:
  Tweaked manifest file. Removed a bunch of hackery from setup.py in favor of setuptools.find_packages, since we're using setuptools anyway. Addresses bug #177.
  Abstracted email resetting during the email change process onto the AccountForm. Addresses bug #173.
  This will include non *.py files in our distribution for setup.py, easy_install, pip, &c. purposes.
  Removed python requirement line from setup.py, since easy_install and pip can't do anything with it and will choke on it for e.g. pypy.
  Correction to waldo login view to pass the request into the login_form for GET requests as well.
  Added release notes for 0.9.1.
  Merged the contribution information from the ithinksw.org philo wiki into the documentation.
  Removed philo.models.Tag entry from the docs.
  Incremented version number to 0.9.1rc and cleaned up README a tiny bit.
