Added tag 3.0 for changeset 8e8c50925f18
Bumped to 3.1 in preparation for next release.
Update documentation to reflect that ez_setup.py moves. Fixes #155.
Add an actual curl example (for easier copy/paste).
Removing the contributors file. While the project is immensely grateful for each and every contribution, a flat file of contributors is an extra burden for maintenance and has the potential to leave some contributors unacknowledged. Given the detailed use of the source code tools and references to the issue tracking systems, the actual contributions of each and every contributor, large or small, are transparently described. Thanks go out to all.
