Subject: [PATCH] _scroll_notebook

With the addition of 043_notebook_scroll.patch in gtk+3.0, it is
possible to switch tabs with Alt+mouse wheel from anywhere on the
notebook. This patch prevents vte from interecepting the signal.

Corresponding GTK+ bug: GNOME #145244

Gbp-Pq: Name 01_scroll_notebook.patch
