bump_release.py

# Very hacky script to bump the version when cutting a new release.
#
# This does the following:
#
# 1. Edit the version number in the 3 places in the code it's specified
# 2. Commit the change to git
# 3. Tag the commit with the version
#
# Note - this assumes that you will *immediately* release the new version,
# if you make changes before doing so, the tag will not match the release.
