Detailed Description

Handles document backup to allow restoring if there is a crash.

Manages on-the-fly backup of documents to be able to restore gracefully in case of a crash.

There are two parts : one that replicates the on-disk part of a document when it was loaded, and one that saves all the command that have been applied.

TODO : update the document part each time the user saves the document. This way there will be much fewer operations to apply if there is a crash. However we have to be very careful in case of the user saving, and then going before his "saved" point in the undo / redo list. Maybe we should keep the previous document saves somewhere and reload from the correct document save according to our position in the command stack.
