Make it possible to move mappings

Move mappings by context menu. Select new parent by QComboBox with
available paths, items separated by "/". Note that hell will break loose
if a mapping name contains "/". Will be fixed later.

Since mapping views don't have setSortingEnabled(), make
SmTreeModel::addRow() sort items.

This fixes a long standing bug in SmTreeModel::reparent(): Since it
alters the model, newParent has to be a QPersistentModelIndex to stay
consistent.
