Yea, I kind of slowed down updating/changing all those modules.
Generally they work, right?  Some of these modules will read all the
data into memory, so really big sites list might cause memory problems.

If there's any that seem to have a pressing need for a change, let me
know.  Otherwise, I don't really intend to do much.  Seems this site
list format won't live much past 5.0 in it's current state, so at some
future date, *all* such modules will have to be revisted.

Currently, I'm trying to track down NVIZ memory leak in Keyframe
animation.  My initial investigation points to the ogsf library, but I'm
not sure.
