After pressing Ctrl+V, the B-1B would spawn new, uninitialized views
that would become selected after pressing 'v' enough times. Ctrl+V
would switch between the cockpit and Offensive Systems Officer views.
This patch removes the overriding and the spurious views, so that
Ctrl+V always selects Cockpit view as in all other aircraft, and
introduces two new key bindings instead:
o - Offensive Systems Officer view
s - Sniper Pod view
