Add autosave function to Okular

Nitpicking about a word?

What Wen would like to add is probably almost the same as Kate does.

When the user starts editing a document, Kate creates a backup of the document 
file, which contains all changes made by the user (with a delay of a few 
seconds).
When the user saves the document, the backup is not needed.
But when Kate crashes (or is killed), and is then restarted again, Kate can 
offer to load the changes from the backup file, so the user looses at most a 
few seconds worth of work.

I can very well imagine having this in Okular.

Cheers, Laura
