Subject: [PATCH] [ROSLOGIN] Add a first (unfinished) version of my script to
 migrate the user database from Drupal to RosLogin.

I want to use this opportunity to clean the user database from inactive users.
A user is considered inactive if it is older than a month and has never been active in either Drupal, MediaWiki, phpBB, or JIRA.
Consequently, deleting it would not cause any loss of information.
However, it keeps our future LDAP directory small and may fix possible name clashes due to the new stricter username rules.
