[osg-submissions] Added LightPointNode pointSprite flag to .ive & .osg write/read methods

[Robert Osfield]

Hi Wojciech,

I've now merged your changes, and added version testing into the .ive
code, I've attached the the files I changed for you future reference.
The .osg plugin doesn't require versioning as its ASCII based parsing
is very flexible w.r.t versioning.

Robert.
