[yt-dev] Make the default camera lens the perspective lens

[Cameron Hummels]

I believe the perspective camera is the most intuitive, and if the speed is
similar to the plane-parallel lens as suggested, I am all for switching the
defaults.  But it may mean we need to tweak some of the cookbook recipes
because many of them were made with the plane parallel lens in mind.
