Remove unnecessary QtQuick 1.1 effectiveLayoutDirection, effectiveHorizontalAlignment and anchors.mirror properties

* these properties are seldomly used
* they confuse developers that do not care about right-to-left user interfaces
* LayoutMirroring.enabled property can be used instead to determine if mirroring is enabled
* if needed, you can easily determine the effective layout directions and alignments
  with a little bit of JavaScript:

function effectiveLayoutDirection() {
    if (LayoutMirroring.enabled)
        return (listView.layoutDirection == Qt.LeftToRight) ? Qt.RightToLeft : Qt.LeftToRight;
    else
        return listView.layoutDirection;
}
