Undefined index in imageeditor_enabled() line 1089

First thank you for this great module, that exactly points my needs.

In content types containing an file field, you get a notice in node edit mode over all image editors, points to an undefined index in line 1089 of the imageeditor.module. The image editor module seems to listen to the file fields beside the image fields (maybe an interesting handle for the aviary vector issue and store vector grafics in file fields?). The transmitted patch wraps the assign of the $settings[$codename . '_enabled'] variable with isset(), so that only setted variables affect the returned value of imageeditor_enabled($settings). Hope this helps a little bit.
