Cleanup: implement proper Qt-model semantics in WeightInfoModel
- Use a beginResetModel()/endResetModel() pair instead of distinct addRows / removeRows pairs. - Reuse the update function in the constructor(). - Let "rows" be the number of rows, not the number of rows minus one. - Remove updateInfo() function as it does the same as update().
