Deletion of objects:

- automatic delete of mandatory ext keys, and if the option is set in the data model (I've set the "manual" option by default, and the "auto" option for links)
- automatic reset of optional ext keys (several keys could be updated on one single object)
- takes into account the user rights
- security against the use of page arguments when the automatic deletion is not allowed
Known limitations:
- does not check that resetting an ext key could affect the lifecycle consistency (e.g. delete a workgroup referenced by a ticket)
- does not check recursively on the automatic deletion, which should not be a problem given the current data model (TBC)
