Make it possible to set QTextOption::WrapMode for the item delegate

Currently QTableView has a setWordWrap() function that takes a bool that specifies whether the text should wrap at word boundaries or not. However, short of subclassing QItemDelegate and rewriting parts of it there's no way to specify that the text can break anywhere. It would be nice if it was possible to either in the delegate or the view used to specify the QTextOption::WrapMode explicitly.
