[osg-submissions] Preserving OpenFlight Object record data

[Robert Osfield]

Thanks Paul,

I've merged your changes, but changed the OpenFlight reader code so
that is uses a new bool held in
Document::get/setReadObjectRecordData() to decide whether to read and
assign the object records or not.  I've set this to off  by default to
retain the original functionality, with ReaderWriter::Options for
enabling it via -O readObjectRecordData .  If the prevailing will of
OpenFlight users is that this should be on by default then I'd be
happy to change, in general though I incline toward preserving
original behaviour hence the settings I've gone for.  I've added
mention of this new variable on the wiki's OpenFlight entry :

Cheers,
Robert.
