Add lens shift support for the camera and the perspective projection functions

Browse Source 
As Blender docs describe it so nicely: Using lens shift is equivalent to rendering an image with a larger FOV and cropping it off-center.
This can be quite useful for architecture renderings, but I guess also has it's use in other situations.
Note: Didn't make the ICameraSceneNode functions pure virtual so users don't have to update their cameras for this
Also some change in serialization - same as in other places by now, do use existing values as defaults values when they are not found instead of resetting them to 0.
