"Changes to provide rudimentary support for OF 15.8 light point
animation palettes. This change also includes light point palette override
support for external references. This is the last of my code changes to
support OF 15.8 in the flt loader. Barring bugs, of course, knock on wood.
The gist of the animation palette code is to create ref_ptr'd
osgSim::BlinkSequence objects for each palette entry, and then pass them on

palette entry. This should be conservative of memory (not that I expect the
animation palette to be extremely large)."
point appearance palette to the OpenFlight loader. Both are 15.8 features.
I also added parsing/comments regarding other things that have changed for
v15.8."
