Drupal Autosave Module Without TinyMCE

The latest release of the Drupal Autosave module (version 5.x-3.2) was made with the explicit intention of making it work without the presence of the TinyMCE wysywig editor.

Sadly, this did not work out for me. Fortunately, the fix was quick and easy. I've posted it here, and also on their bugtracker. This diff applies against 5.x-3.2.
