> Quick fix for versions browser.

> Note that I think that the interaction that results in selection changes should be implemented in the widgets, not the models.
>
> Is [shift] pressed?
> Is it a drag?
> Is it a click on an already selected item?
>
> All these things belong into widget code to keep model code simple. For example, I think that we should also move the logic behind range selection from MessageTrace into the AlternatePluggableListMorphOfMany. So other models (or tools) could benefit from it.
