I made some significant changes to the fedora_bz.py script today.
This updates the docs to reflect current usage of the script
after these changes. It also changes the changes-contingency
page to recommend using the script - currently the page does not
say to use the script even though it has the capability to do
the necessary work for the change deadlines.
