Add subscription screen
The idea is to have a «Subscription» page in the menu (with its own ACLs), showing either information about how to get a subscription, or information about the subscription stored in the LDAP. It must be able to import this information from a file sent to subscribers, not sure yet if it should be LDIF or JSON. Apart from the import field, information is read-only.
The information is stored under ou=fusiondirectory.
