    Bug 797984 - Infinite loop while Check&Repair AR and AP accounts
    
    If using the Check&Repair option from the Chart of Accounts on 'Account
    Receivable or Payable' add has a voided transaction will cause an
    infinite loop.
    
    This occurs from checking the transaction split amount is zero in
    gncScrubBusinessSplit and trying to delete it. As the transaction is
    read only as a result of being voided this fails so add a further
    condition for the 'else if' statement to include !is_void.

    Allow the Check&Repair to be cancellable on a Register page
    
    Add a callback for a keypress event when on the Register page that
    checks for the Escape key and presents a dialog to confirm whether to
    abort the Check&Repair. A similar dialog is used if you decide to quit
    Gnucash while the Check&Repair is still running.

    Allow the Check&Repair routine to be cancellable from CoA

    Gnucash while the Check&Repair is still running.
