Refactor the new QXYSeries::pointAt() -> QXYSeries::at()...
Refactor the new QXYSeries::pointAt() -> QXYSeries::at() QML API already had XYSeries::at() for the same functionality. Also, at() is a common method for returning an item at index in Qt containers, so use that instead of pointAt(). This function was introduced in polar chart refactoring and has not yet been released, so no problem changing the name at this point.
