I've reverted the change, but I'm not keen to make the above changes
because they're not trivial, I don't understand them, and I would
basically be copying and pasting code. I suspect we could have license
issues with that. If anyone knows different feel free to chime in.

For future reference, here are the known work-arounds for this problem:

1. At the command prompt: defaults write org.gnu.Emacs NSAppSleepDisabled -bool YES

2. Right-click on the Emacs icon and select 'get info' and tick the
   'Disable App Nap' checkbox. (Although I don't get that tick box...)

3. Run in daemon mode: Emacs as a daemon has no GUI so app nap
   is disabled automatically.
