    - Move it's implementation to gnc-file with the rest of the file actions
    - Ask user confirmation
    - Don't ask to save before reverting

commit bfce5d840d990f2d762d26a61eb4d915f310f813
Author: Geert Janssens <janssens-geert at telenet.be>
Date:   Fri Dec 11 12:05:15 2015 +0100

    Have a more generic mechanism to set Save action's sensitivity and use it for Revert action as well
    
    So far the Save actions was more or less treated as an exception.
    The new code enables/disables selected actions based on the dirty
    state of the book.
