    More fix-ups for the renumber subaccounts dialog.
    
    Add more invariant checks for safety.
    Suppress the '-' in the account-number format if the prefix is empty.
    Set the value for the interval GtkSpinButton so that it won't be 0 on startup.
    Fix the step-increment and page-increment property names in the builder file
    so that they have an effect.

commit 7daad042d0b5e426d0c5153d71abf69bd071fd4b

    Bug 725054 - Re-numbering sub accounts crashes the program
    
    g_strdup_printf ("%s-%0*d", prefix, num_digits, interval) calls malloc()
    with the number of required characters, which includes num_digits characters
    for the numeric. If the interval is 0, log10(num_children * interval) is
    log10(0), which returns NAN (not a number), which when cast to size_t is
    MAXINT. That generates a malloc error, which crashes GnuCash.
    
    So don't let the interval be 0.
