  -----------
  Apply the deprecation standard to the new GUI2 API

This also removes backwards-compatibility.lua altogether.
It's no longer correct in the general case to add backwards compatibility code to this file, so removing it entirely avoids situations where compatibility code is incorrectly added there.
