[GNC-dev] Disabling of multitransaction selection in the import matcher window

[davidcousens49 at gmail.com]

Have since found out that this is still working, but with some problems in
initially selecting the second member of a selection. Once I have got the second
member selected then adding subsequent transactions to the selection is then no
problem. I have had to do this several times undoing the selction completely
before getting it to stick. Feels to me like it may be an underlying problem
with the GTK-3 library perhaps rather than being specifically a GnuCash problem.
