Lightwave export bug

[dgud]

Arrgh for bad coordinate systems.. :-)

And since you have not reported this previously before we made the new release,
you really don't deserve this.

And I do read the bug-reports thread more often than this..

There is a wpc_lwo.beam @ https://www.dropbox.com/sh/54h7afpm5hvx45m/hcay8uZhgc

Replace the one in wings_dir/plugins/import_export

And tell me if it works as expected and I will add the fix to wings.
