Autosave Plugin

Hi all,

periodical autosave is long standing demand (bug 138373).
While in my regard this is headed in a totally wrong direction [1],
there's nothing wrong with having a plugin that works this way.

Somewhat suprisingly, i couldn't find such a plugin, so here's some
dirty PyGIMP which at first glance seems to do the job. Perhaps someone
gets inspired to create something worth uploading to the registry.

Usage:
- start GIMP from a terminal (so the script's messages become visible)
- toolbox: File->Activate Autosave (activate only once)

Every 30 minutes the script saves backups of all opened images to a temp folder.
The backup files won't be deleted when GIMP exits, so some manual clean-up will
be required from time to time.


have fun,
peter
