    timer: Add ability to enter mins/secs > 59
    
    Linked 'input' signal of minutes and seconds field to its handler.
    Apparently, Gtk.Entry.get_text() returns the actual value entered in
    the spinner as opposed to the Gtk.Entry.get_value_as_int() which
    returns the value after evaluating the range of spinner.
    
    Then used these values to find overflow and carry to the next field.
