Prevent the legend text making the features dialog too wide (#7)
With the Gtk3 port the File System Support dialog has become too wide because the legend text is no longer wrapped. Set the max-width-chars property to specify the natural size of the widget in terms of characters [1]. It is converted to pixels using the average character width in the current font. Also use PACK_EXPAND_WIDGET when adding the label to the box so that if the dialog is resized extra space is used to increase the size of this child widget [2]. [1] GNOME HowDoI / Labels https://wiki.gnome.org/HowDoI/Labels [2] Gtkmm 3.0 Enums and Flags, enum Gtk::PackOptions "PACK_EXPAND_WIDGET Space is expanded, with extra space filled by increasing the child widget size." https://developer.gnome.org/gtkmm/3.0/group__gtkmmEnums.html#ga83727a1b6fed51566dfd5c8e58890dba Closes #7 - Port to Gtk3
