If someone ever git forces pushes to a blessed repo all hell will break loose.

Force pushing on blessed repo's is very bad, but force pushing on forks is very common.

Requirements:

• Enable this on 1 new dummy blessed repository
• Prove you cannot force push to
• Prove you can fork it and force push to your fork.
• Delete the dummy blessed repository
• If that works well, enable it on the real blessed repositories
