Upgrade the Navigation module

Upgrading from version 1.* to version 2.*

Version 2 adds validity date fields to navigation nodes to support NavigationGui module to control the temporal visibility of nodes.

• Update the Navigation module to at least version 2.0.0 in your composer.json.
• Install the new database fields by running vendor/bin/console propel:diff. Propel should generate a migration file with the changes.
• Apply the database changes: run vendor/bin/console propel:migrate.
• Generate ORM models: run vendor/bin/console propel:model:build.
• Run vendor/bin/console transfer:generate to generate the new fields into the Navigation transfer object.

As a result:

• valid_from and valid_to fields are added to spy_navigation_node table.
• Corresponding properties, getters, and setters are added to Navigation transfer object.
