[GNC] Export file lacks document links

[Brook Milligan]

OK, I found what appears to be the way to access document links in the code (see libgnucash/engine/Transaction.cpp).  It seems that the attached patch (untested) will add the transaction link to exported files. 

However, I’m much less certain how to make the import code handle the extra field.  All the callbacks make that code unclear to me.

If anyone has a better sense of how importing works, please let me know how an extra field (doc links) can be added to the process.

Thanks a lot.

Cheers,
Brook
