TODO list for RescueBRU-7.1.1

feature: save config of backup in a backup.conf file to include devices. 
    Check for this file when doing a new backup. Offer to use existing
    config.
    
feature: replace spaces with underscores in new image name.

bug: on restore, the "original drive was" and "current drive is" info
    messages may be blank due to inconsistency in how smartctl
    displays the drive model. the code looks for "Device Model" and
    sometimes smartctl just outputs "Device"
    
bug: when getting a list of images in imageselect() sometime a busy
    server can make the client appear to lock up. Need a "please wait.."
    message so user doesn't panic.

bug: server may appear to lock up when using several functions. Need a
    "please wait..." message for anything that might have to load data
    from the CD.

bug: settings selections submenus don't preselect the current setting as
    the default-item in the dialog.
