Description of Changes
- Adding a default for NewCops
- Adding a test for checking the validity of the default.yml file
This effectively fixes the warning when NewCops are added:

Setting it to "disable" is probably the least disruptive, but if we want to set it to enable I'm ok with that too. I mainly want it set to suppress the warning.
Take a look at the above doc link. I believe that when a cop moves beyond the new status, rubocop will set the default one way or the other, then the NewCop setting no longer applies. I think of this as... set it to enabled if you want to be on the bleeding edge of new cops, disabled if not.
