Add inside some create* methods the setWhatsThis() and setToolTip()
callings. That way the management of tooltips and “What's This” help is
Note: The parameter const QString &toolTip was already used in:
KonfiguratorCheckBox *createCheckBox(QString configGroup, QString name, bool defaultValue, QString text, QWidget *parent = nullptr, bool restart = false, const QString &toolTip = QString(), int page = FIRST_PAGE);
A tooltip (related to Krusader lister) was added, with the text: "If a text file
is bigger than this size then lister will be used". That tooltip is also useful
as an example and in order to perform tests with it.
GUI: A new translation string was added, which is visible on a tooltip and a “What's This” help.
