When deleting a session, it doesn't delete documents that are session-specific.

• create a session (let's say session.id = 6)
• add a course to the session
• go to the session-course
• create a document (this one is specific to the session 6
• go to the list of sessions
• delete session 6
• the session is deleted but the document remains in c_document with a session_id = 6

This probably happens with all other resources that can be session-specific. It has to be fixed for all of them (deleting those resources).
I have added (today) a deletion of session-specific items in c_item_property because it generated a foreign key constraint error, but those records in c_item_property could probably be used to find the resources to be deleted. Otherwise use the code found in the course deletion process. There's probably an exhaustive list there.

The code should be added to the sessionmanager.lib.php::delete() function (before c_item_property deletion).
