* EepGet: Fix byte count for bytesTransferred status listeners

Browse Source 
(fixes command line status)
    * UpdateHandler:
       - Fix byte count display
       - Display final status on router console
       - Don't allow multiple update jobs to queue up
       - Increase max retries
       - Code cleanup
       - Don't show 'check for update' button when update in progress
       - Enhance error messages
