MappingTreeModel Fix: repair parent <-> child relationship

Warning: this commit seems to work, but it doesn't!

Introduce two new tables: mappings_parents2 and pics_mappings2 to create
a real parent-child relationship. The pics_mappings need to reference a
unique mappings_parents_id so the same mapping can be a child of
different parents.

For now only the MappingTree references the new tables. Everything else
uses the old ones. Hence the warning!
