    prefs-dialog: Only save settings when closing the dialog
    
    Currently, each time a modification is made the settings are written to
    the disk.
    
    But it isn't really needed to do it for each changes, saving only once
    when closing the preferences is enough. This saves a lot of disk writes
    when doing several changes for the same setting (like changing the name
    of a search engine).
