From Joson Daly, fix for forward/backward/swing animation handling both 15.8 and

versions prior to 15.8, and...

" Here's another fix for OpenFlight.  The symptom was that ATTR files were
not being read correctly, and the TexEnv on a texture that should have
been set to DECAL was instead defaulting to MODULATE.  The cause is that
the ATTR reader cannot tell by itself what version it's reading (the
version information isn't present in the ATTR files), and instead relies
on the ReaderWriter::Options passed in to get the OpenFlight version.

My change clones the current ReaderWriter::Options and prepends the
appropriate FLT_VER option before the ReaderWriterATTR object is
called.  I also made the parsing of the FLT_VER string and value more
robust in the ReaderWriterATTR itself.  I think I commented things OK,
but let me know if you need me to explain anything."
