* "Delete" menuitem's string improved. (#3531)
* New way for handling of selection. (It's better if RowHeaderHandler takes care about it instead of CasTableControllerW, because we need to know the indexes of the selected rows when the row header popup menu is created, and at certain browsers the event on CasTableControllerW will be handled later, so the Delete menu's string will created accordingly of the previous state.)
