port-to-gtk3: Use Gdk::Cursor via Glib::RefPtr<> (#7)

Starting from Gtkmm3 Gdk::Cursor objects cannot be constructed directly,
but instead you have to get a smart pointer to an instance by calling
the static member function Gdk::Cursor::create().

Gdk::Cursor::create() returns a Glib::RefPtr<Gdk::Cursor> object.

Gtkmm3 always uses Glib::RefPtr<Gdk::Cursor> in its interface and never
plain Gdk::Cursor.

    "... Gdk::Cursor are now used via Glib::RefPtr."
