[yt-dev] na => np in 3.0 and 2.x

I think we should go for 2.5 release.

BTW, an Athena user just found a bug where certain simulations that don't
have equal sized grids will not work.  I didn't think this was possible but
it turns out it is so they or I will be addressing that in the coming days.

If the release is >1month, I would also like to push in some
rendering/AMRKDTree improvements.  If it <1month, I don't think I'll get to
it.
