Add Camera::LookAt
...
This is identical to the POV-Ray look_at keyword for cameras. In fact, I stole the code almost directly from them… It's super handy for panning and tilting the camera towards a particular point, and saves me having to do dubiously accurate direction vector calculations by hand.
I still need to figure out what exactly this math is doing.

Finally! :D Verified (mostly) and carefully thought through by looking at the
Pov-Ray code and doing the linear algebra by hand. Fun times.

I don't really know if this is correct; I have not verified it
