Adding objects to the library list for use with xml.

I think at present the problem is that we still do not know exactly which of the old BGLC commands still work if used in a new mdl file. Only after that has been established we could try to convert the old macros directly. I think its exactly that was Arno tries to do. I can only hope we will find out before we have to adapt to the next version of FS... It seems not to be too difficult to emulate many of the old macros in GMax, at least those which are not too sophisticated. For the time being, this is probably the easiest way. osman
