Still tracking the `v1.0.1` tag for now, just reverting all the unnecessary
style changes that created a diff with upstream.
(cherry picked from commit 6c78170d8c)
Change the entire navigation system.
Remove editor prefix from nav mesh generator class. It is now used for baking
at runtime as well.
Navigation supports obstacle avoidance now with the RVO2 library.
Nav system will also automatically link all nav meshes together to form one
overall complete nav map.
