Autosave

[naevtamarkus]

Dear devs,

I am getting segfaults for some reasons (SIGSEGV in QInternal MimeData::formats()) probably because of the machine going to Sleep mode (Linux) but this is not why I open this. What I would like to kindly ask is for an auto-save feature (e.g. in /tmp, say every minute?) that keeps my edits safe.

I have just lost an hour-worth of editting, and unfortunately lost my habit to do Ctrl-S every second minute some years ago.

Thanks for a wonderful editor!
