Camera Lock View v3

This makes view3ds camea follow rotate/pan/zoom/dolly operators.

Now addes support for almost all view operators...
- auto-depth preference now works
- smooth view navigation supports  too.
- view selected, all & numpad operator work too.

Unless some other problems come up I consider this patch basically finished & ready for review.

Hi, looks like you have specified a wrong base url:

Which leads to a 404 on any of the attempts to look at sidb-by-side diffs:

Could you fix that?

Wouldn't it make sense to set camera here too?

No, what happens in this case is smoothview is not dealing with change cameras,
Its just interpolating ofs/viewquat/dist.

In the case where camera locking is used (checked in
ED_view3d_camera_lock_init), we want the camera/view to stay unchanged - and
just copy from the rv3d to the camera object on each smoothview update,

I can give more comprehensive comment about this :)
