[GNC-dev] Bug 796778 Feature Request Multiple Selection in Import- matcher

[Robert Fewell]

David,
Why do you not as a start change the tree view selection from single to
multiple, you will see that in the dialog-import.glade file, that way you
can select multiple lines.
You will need to alter the selection call back as you need different
functions that use a list of selected rows.
