Remove forced console.logs when returning false when inserting/deleting a row

I want to use the default contextMenu that is provided by this library, but I want to handle the events in a custom manner. Therefore I return false in my onbeforeinsertrow and onbeforedeleterow functions. However, returning false here always results in an unnecessary console log by the library:

// Onbeforeinsertrow
if (obj.dispatch('onbeforeinsertrow', el, rowNumber, numOfRows, insertBefore) === false) {                
    console.log('onbeforeinsertrow returned false');

    return false;
}

and

// Onbeforedeleterow
if (obj.dispatch('onbeforedeleterow', el, rowNumber, numOfRows) === false) {
    console.log('onbeforedeleterow returned false');
    return false;
}

Can these be made optional/removed?

Search the JavaScript source for the onbeforeinsertrow and onbeforedeleterow dispatch blocks shown in the issue. Check the surrounding event-handling behavior and verify that returning false still prevents the row operation without producing the unwanted console output.
