[GNC] Fixing bad Bayesian data

[Geert Janssens]

GnuCash 3.x also has a new tool that allows you to erase bad bayesian data. 
There's no need to dive directly into the data files to make changes. This was 
contributed by Robert Fewell.

This tools is called "Import Map Editor" and can be found under the "Tools" 
menu.

Regards,

Geert
