Add Scrollable property to ElmSharp.Entry

Warning: enabling the Scrollable property changes the internal hierarchy of
the entry (via elm_widget_resize_object_set()). This in turn causes all kinds
of side effects, i.e. changing the background color via
    ElmSharp.Widget.SetPartColor("bg-default", color);
no longer works.
