See gazebo-tooling/release-tools#711
Supercedes #50

One last thing that we could fix in follow up PRs. Everywhere that's user-facing, like documentation and UI, should use "Gazebo". Everything that's in the code should be gz

I just tested this branch with ign-math, and it breaks because ign-math has already switched to the gz/utils/* headers but not the gz:: namespace

As discussed, to reduce the number of rounds of PRs, we'll go ahead and merge this series topologically, leaving downstream libraries broken in the meantime. We'll plan to do it at a time that disrupts the least people and will test all PRs together well before doing so. This should save us more rounds of PRs.

I found a bug in my script, that's been fixed, and propagated across all repos.
