Added 'Still View', a new core view, number 8.

Browse source 
This view is like Helicopter View except that it does not change the view
heading to match the aircraft, which makes it work much better for vertical
flight, e.g. with the shuttle.

The new view is disabled by default.

Nasal/view.nas
    contains the new view config.
defaults.xml:
    Added view 8 to list of views for which we default to Helicopter view's
    target offsets (so that they look at the centre of the aircraft).
