More fixes to MappingTreeModel

Fix move, addChild and such. Rename Fields and Roles to more speaking
names, but that revealed a much deeper bug: the ParentID isn't really
the parent_id, but the mapping_id. That could explain a lot.
Nevertheless, it's still faster to repopulate the model after moving
oder adding children instead of calling removeRows and insertRows.

Another non-working commit... :(
